知识付费是一个伪需求

从分答开始,互联网似乎掀起了一股知识付费的热潮。然而在我看着这股热潮实在是个大大的泡沫,只不过是乘着支付宝和微信支付普及的东风创造出来的一个伪需求,热乎劲一过估计也就偃旗息鼓了。

互联网的精神是开放共享,而知识付费则是建立了一个付费的围墙,显然和大势是相悖的。

回答欲

对于付费的问题和收费的问题,人们的回答欲望是有天壤之别的。有时候看个问题不错,就是按耐不住体内的洪荒之力,想写上几千字。但是突然有个人过来说,来回答这个问题给你5块钱,瞬间就不想答了。。

本来回答问题实际上是自己的一种精神享受,而一旦加上钱以后,人们潜意识里就会觉得这是再给别人干活儿了,所以几块钱反倒会坏了事。

真正有价值的东西要么根本不会公开传播,要么那就是要出书立传,流芳千古的,会卖着屈屈几块钱?

比如说我,去开一场live,5块一个人,有1000人来听,那我也得准备上个一两天吧,但是我能教啥呢,我可以说一些爬虫的基础知识啥的,但是说深了,我也不能暴露我们的业务数据吧?比我级别高一点的,手里期权一大把,会缺这点钱?会有时间挣这点钱?哪怕是个愿意分享知识,建立自己影响力的人,那肯定会去写博客啊,这样才能扩大影响力嘛

眼下的红火

付费问答现在还是一个噱头,所以还会有一些名人/大V来做问答,但是这更多意义上算是粉丝经济,名人要的是曝光度,而不是在乎那屈屈几款钱。名人的话更多的是增加了曝光,这个潜在价值太大,不过说了。但是主流的开live的人,如果是邀请来的人水平够了,那人家根本不缺这点钱,花这么长时间就能在这么一点人之间扩大影响力太不值啊,也就图个新鲜。如果邀请来的人愿意长期赚live这个钱,那水平肯定高不了啊,不然谁吃这点苍蝇肉啊,所以就是大量的零基础入门python了。还有就是要想让受众广,就只能开这种基础课

在线教育

广义的说,知识付费也包括 K12 在内的在线教育,这部分我倒是非常看好。毕竟有的人就是学习能力差,或者说愿意听人嚼碎了再讲给他听,这种需求在线下是刚需,把线下的培训搬到线上,能够更好的传播,能够突破线下教育的地理限制,相信会有很好的发展。

付费问答的水平悖论

现在的这些付费问答就是听众想花5块钱卖价值百万的商业问题,回答的人要么不懂,要么也没法说。

一样,你想聊的人不稀罕这点钱,稀罕这点钱的人你不想和他聊

真正的知识付费是几百万的商业策划,几百万的UI设计。公开的问题可能是 “前端程序员怎么规划学习路径”,然而付费问答则可能是现在你花五块钱就想问“我现在会js,会一点css,会一点vue,blah,blah,”

真正的知识付费

其实知识付费早就存在。小说就是最好的例子,并不是什么高大上的新东西

对头条的思考

读张一鸣微博

可假设某位下属提辞职,感受如是『很可惜』『很在意』那么应现在考虑如何给增加回报和空间,相反,如觉得『也好』『更好』甚至轻松,那应考虑是否做出调岗或辞退。

时常看看旧闻,就知道媒体多么不靠谱

大剑无锋大巧不工

在全网的上抓取分析提取信息,遇到的大问题就是 spam 以及 spam 的高级形式软文或者枪文,pangerank 是网页的投票,sns 利用可标识的人行为来投票,sns 平台之外还有好方法吗。

风景长宜放眼量。往事不可谏,来者犹可追。

他应该是一个类似张小龙一样,技术出身的优秀的产品经理

反思

阿里的月饼风波过后,一鸣好像说过:“我们中秋节就不发月饼,因为优秀的工程师不会在乎那一盒月饼的。” 其实这句话就非常傻,优秀的员工可能这样想:“一盒月饼才多少钱,公司连这都舍不得,在其他事情上会舍得为员工付出吗?”。月饼这种东西显然是 ROI 非常高的一个员工福利,所以不要为了彰显和阿里不同而故意说反话。当然,实际上头条的福利很好,不光有月饼,过年也有礼物。

Google 的价值观就很短:Don’t be evil. 以至于大家都知道。而百度的价值观也很短:简单可依赖。虽然不管是 Google 还是百度都没有很好地践行他们的价值观,但是至少起到了宣传作用吧。头条的价值观太长了,而且是五六个独立的词语,到现在我都记不下来。平均下来头条员工在头条的时间可能连两年都不到,你让人记这么长一大串东西,你又不是社会主义核心价值观。

the ipinfo story

what does this guy do?

  • find a easy question, however cumbersome question on stackoverflow.com
  • answer the question with a solution of his api, with full demo codes of usage.
  • so many amateur programmers are not capable of or too lazy to build such an easy api, his answer and api took off.
  • make money

Why he succeed?

  • > no one talks about the easiest way to “Make What People Want”: Make What People Ask For.
  • answer many questions related to this, about 1 question / 20 days
  • his answers give the whole solution and full examples
  • his design is simple, reliable, fast

as pointed by one hacker news comment, it’s a very competitive market, however you don’t have to own the whole market, a small share is just profitable.

Comments on hacker news

1.

I see the author is posting the same thing every 20 days or so, so here is the 0 marketing…

2.

Kudos to you guys for building this. There is always a lot of scepticism from people on “why would anyone pay for this” . Reality is not everyone has the time or resources to build their own kit. There are literally 1000s of businesses on the internet that that are in the business of selling “time” or timesavers and removing the risk of maintenance, ongoing support.
Keep improving this and with the rise of web personalization, the demand will continue to grow.

3.

Just some rough calculations. Assuming the worst-case scenario, everyone in the highest tiers (the cheapest per request), 250M daily requests means he makes
400 * 250M / 320K = $312,500 per month.
Or $3.75M per year.
Not counting the expenses.

4.

I think the most common business model for a website such as this is to offer premium services like:
1) more accurate details
2) fraud protection, if the ip is known for fraud or spamming
3) increased rate limits, etc
Just the top of my head s.. I’m sure you i can think of many more..

5.

I use ipinfo.io mostly to see my own public facing IP address and for me, it’s 2 reasons:
– I somehow can remember that domain. I don’t have to google “my ip” and dig through weird domains that change all the time
– The design is clean and simple. Not too many information, no ads, loads fast.

6.

This has worked well for me, too. I saw an influx of “How to offer a time-based trial version on Android” on SO and developed a trial SDK as an answer: https://www.trialy.io/

developer mis-charging

I find it a little funny how unrealistic people can be when evaluating the cost of their problem. Take this one for example: “We have hundreds of images uploaded to our app each day. The issue is some of these images have text that we want cropped out.” — willing to pay? $75/month. Baller!
Chances are this is a problem for a data-mining / ai-training platform that wants to create a better image set. They are charging clients tens of thousands of dollars, and yet willing to pay $100/month to improve the data. lol

On the other hand, it can also go the other way. Non-technical customers don’t actually care how hard something is to build, as long as it solves their problem. So it often surprises engineers how a 1 day script can make lots of money for them.
Freelancers often make the same mistake–charging by what it costs to them, plus a little bit more. You should charge how much value it brings to the customer, not how much it costs you to make. Easy to say, hard to do.

电商在中国

虽然电子商务已经在中国发展壮大,但产值还未达到惊人的规模,海量的日常服务仍在线下进行。例如中国80%的酒店客房还是线下预订。中国消费者青睐电子商务的原因不是它能带来便利,而是它比实体店的经营公开透明得多,腐败因素少得多。
正 如李开复所说,按美国标准评价,中国的实体商家普遍效率低下,大肆吹嘘的行为比比皆是。他指出:“美国有几百年公平竞争的传统,商界相对比较公平透明。” 可中国截然不同,“如果要出售房地产,交易根本是不透明的。如果想买二手车,也没有像Consumer Reports那样的独立调查机构出具质量报告,或者勇敢的消费者出面披露汽车安全问题。”李开复认为,电商无需中间商和创造声誉的系统,让交易更透明、更可信,“所以,基于社交的手机解决方案会好得多。”

关于电商的思考

淘宝占据了服装和美妆两个利润率最高的品类,而京东只能靠家电和3C产品这两个没有什么利润的品类,当当和亚马逊靠书更是不行,而且还有苏宁易购(阿里注资)穷追猛打,所以很难搞啊。

买手店(搭配)会不会成为一个新的电商平台呢?什么值得买是一个很好的导购平台,但是总的来说并没有占据利润率最高的两个品类,而且是单个SKU的点评。

关于推广和冷启动的一些想法

总体思路主要两个,一个就是借助于搜索引擎,另一个就是借助于 SNS。不过两个方法并不是完全对立的,比如说在知乎的答案中提到自己的公众号或者 app,那么既是一种社会化推广(粉丝会看到),也是一种很好的搜索引擎推广(知乎的权重很高)。

获得新增用户无非两个手段,一个是主动拉新用户,比如去 QQ 群中宣传;另一个是被动获得,坐等其他人通过搜索引擎发现自己的网站。

推广的平台

一些权重比较高的网站

  • 知乎
  • 知乎专栏
  • 微博
  • 豆瓣
  • CSDN 一个推广芯片的例子
  • cnblogs
  • 简书
  • 贴吧
  • GitHub。在 GitHub 仓库中的内容似乎也不错
  • medium
  • V2EX

可以提交链接的网站

  • reddit
  • Hacker News

发送自己文章链接的平台

  • QQ 群

SEO

为什么需要 SEO?因为你缺少一个让用户可以持续接触到你的产品的渠道。问题在于Product Hunt 和Hacker News上的用户可能并不是你产品的目标客户,他们仅仅是了解今天发布了什么新的产品,然后继续干他们自己的事情。那些真正的用户,是很难靠这种方法获取到的。

交换友链这种行为基本上已经过时了,现在是内容更重要。所以首先你需要写点什么,哪怕你付钱让别人写也好。

一个可行的策略:

  1. 写一些有趣的,有用的东西
  2. 将站点的链接,放到你想主推的关键词里面去
  3. 在内容平台上进行发布

内容

  • 当搜索一个问题没有好的文章或者回答的时候,自己写一个,并把连接贴到对方的评论区
  • 自己写了一个文章之后,搜索相关的关键字,然后把自己的文章贴到评论区
  • 把链接提交到 reddit 等社区

知乎

  • 在知乎答题,要带上自己的公众号、头条号和博客
  • 如果你确信自己答得比较好,可以技术性踩其他的答案(这个问题里的其他回答都是垃圾,实名反对最高票的答案)
  • 答案本身需要优质

头条

头条上的不少评论文章并没有什么深入的观点,甚至根本不足以称作一篇文章,但是因为蹭热点,反倒评论里面很多宣泄情绪的人,甚至都不读文章,直接开骂的,这样反倒刺激了推荐系统把这种文章推给更多的人。

How to publish your game

A few thoughts as someone who has developed games for iOS, Android, and the web:
In today’s world, if you want to retain implicit ownership of your product’s name, a simultaneous triple-platform release is not optional, it is required. It must be performed in precisely the following way, or your launch will fail:

  • Register your game’s domain before announcing it to the public.
  • Next, upload your iOS app to iTunes Connect and wait for up to one week for the app to be approved.
  • Next, upload your Android app to the Google Play store; approval only takes a few hours.
  • Finally, make the web version public, and announce the game along with links to the mobile versions.

If you deviate from this order, then you’re screwed. One example: I released a game on the web and waited one day to upload the Android version to the Google Play store. I figured that gave me a little extra time to test and check for bugs, and what’s the rush anyway? Nobody could steal a game in just 24 hours, right? Wrong. My app was rejected because Google insisted my app was attempting to impersonate another developer’s app. The other developer’s app was simply my own website, stolen line for line, tossed into Phonegap, and released the same day as my website. I explained this to Google in the appeal form, even including a link proving I owned the site the other developer stole it from, and they rejected my appeal without checking the link – I could clearly see in my server logs that they never clicked on it. Google does not allow you to file a second appeal, so I had to give my app an awful name no one would recognize it by, and the clone received all the downloads and glory thanks to the buzz my website’s name was generating for it.

Another example: I was the first to publish an iOS app with the same name as my website. After the app had been waiting for review for four days, I figured it would be approved any moment now, and that it was safe for me to launch my website. I launched, and it turns out that Apple’s app review process is not FIFO, because two days later, a clone with the same name and all the code stolen from my site was already approved for iOS, yet my own app was still waiting for review. My app was then rejected a few days later because it had the same name as an app that stole my code… again.
Gabriele Cirulli is an extremely unlucky man stuck in an extremely unfair landscape, and I cannot fault him for wallowing in the first of the five stages of grief. If Flappy Bird’s alleged $50,000/day income can safely be assumed to be the average earned by the ads on any given #1 iTunes free app, then the entity which first claimed the name “2048” in iTunes Connect is currently a millionaire, because 2048 was at the very top of the iTunes free app charts for weeks. Gabriele seems to believe or hope that the masses will see his “repost” of his own app and be stricken by the desire to do the ethically right thing and uninstall all of the rushed clones and install the legitimate version and play it with all the fervor and excitement as if the global 2048 hype still currently existed. Unfortunately this will NEVER happen.

On a side note, Phonegap is only getting worse over time. Typical Adobe rot is setting in; the last version had a catastrophic bug causing the xml manifest to simply not be read during the build process, because a critical “for” loop was referencing the child element of a nonexistent variable. They swept this under the rug; countless hapless developers were mindlessly releasing broken apps during this period. Half of Phonegap’s documentation refers to “Cordova” and executing “cordova” on the command line where it should say “Phonegap”. Commands that have different names between Cordova and Phonegap are still documented as the Cordova equivalent, so one must use Google to find other people who searched for hours until they themselves came across the explanation that the same command in Phonegap requires the use of a completely different word. It is an absolute trainwreck, but aside from that, the primary issue for consumers now is that apps built with Phonegap no longer work correctly on newer versions of Android and haven’t for months, which is why Gabriele’s extremely simple and resource-minimal app is currently getting a bunch of 1- and 2-star reviews in the Google Play store with complaints about the speed.

翻译

作为一个曾经为iOS,android,web开发过游戏的人,下面是我的一些经验:
在现在的世界里,如果你想获得你产品名字的所有权, 那么需要近乎同时的在三个平台发布, 并且你必须这么做. 而且你得严格的按照下面这几步做, 不然你的发布就失败了.

在公之于众之前注册你游戏的域名
接下来,上传你的 iOS 应用到 iTunes Connect 然后等待多达一周的时间知道通过审核
然后上传你的 Android 应用到 Google Play, 大概只需要几小时就能通过
最后公布你的 web 版本, 然后附带着移动版本的链接发布你的游戏

如果你偏离的这个顺序, 那么你就完蛋了. 举个栗子, 我现在网上发布了一个游戏然后才在一天之后才上传到 Google Play 市场. 因为我觉得我需要更多的时间来测试和检查 bug, 而且着啥急啊? 总不能有人在24消失之内就把我的游戏偷了吧? 错了, 我的应用被 Google 拒绝了因为他们坚持认为我的应用正在模仿其他人的. 其他开发者的应用完全是把我的网站一行不差的包装了一下(用Phonegap)。我向google解释了这一切

总结

投放自己文章的渠道:

  • 开发者头条:由于截图的时候没有新发文章,之前那篇秒杀架构实践发了之后博客 80% 的流量都是从头条过来的,而且质量很高,不得不点个赞。
  • 并发编程网: 并发编程网是由阿里大牛清英(买了那本《并发编程的艺术》就被圈粉了)创办的,其中的文章质量普遍较高(导致也会有一点写作门槛)。由于网站的流量也比较高,只要你的文章质量不错肯定会得到好处。
  • 掘金:掘金这两年也比较火,是专门做开发者内容的,也是网站流量不错。
  • 开源中国:开源中国的博客也不错,自己也有代码托管,但我还是更喜欢用 GitHub,一般上了编辑推荐都会有不错的访问量。
  • V2EX:大名鼎鼎的 V 站,其实受众较少,正因为如此也形成了独有的文化,因此也是我每天比逛(摸鱼)的网站,由于受众大多是开发者所以也能得到很多有用的反馈。
  • 大佬推荐:最快捷的方式其实就是口口相传,其中当然是大佬的效率最高。之前有个纯洁的微笑、程序猿DD 都投过稿,也能带来不错的流量。
  • 简书:本来不想推荐简书的(之前的事件以及现在鸡汤太多),但是流量还可以,现在就纯粹当做博客备份的工具了。

简书上一些低端的教程似乎在google的结果中能够排得比较靠前的位置,比如这篇,简单的利用scrapy爬取链家数据的文章,类似的文章还有很多。

profitable side projects on HN

Udemy

I made a course on Udemy on how to make complete web applications without writing code using APEX.
Link and free coupons:
https://www.udemy.com/create-web-apps-with-apex-5/?couponCod…

Expenses:
$100 for a nice microphone (not necessary) but didn’t want to record a bunch and have it be garbage $100 for Screenflow (to do video editing). 20 hours time (split across a couple of weekends

Profit:
I’ve made $1405 on it so far. It is almost completely passive income.

Proof:

If you know any of the topics in the Hot Topics list and can do desktop recording, maybe you should think about teaching others and making some side money while doing it. Best of all, the Udemy community is awesome. They are very supportive of each other.

Ebay crawler

A year. I was spending way too much time on eBay, so I wrote something for myself that would scrape the web pages and use a kill list to filter out the junk. I wanted a better UI to add words to the kill list and realised I could make money via the eBay affiliate program.

So I took two months off between contracts and wrote the first version of AuctionSieve – http://auctionsieve.com

There was a D&D forum, the Acaeum where a bunch of people started using it and giving feedback.
It was making me money from day 1 but it probably took about a year to repay that 2 months of time investment.

It’s now been 13 years(!) and it still makes me money – not enough to live off (the payout calculations from eBay have changed several times) but a nice chunk of change. And I only have to occasionally prod it. And add the occasional new feature.

Inovices

I’ve worked over a year on https://www.boxfactura.com/ which is a special email service for invoices in Mexico.

It has been profitable since January after quite some legwork, on the technical side as well as the sales and persuation side.

reply by emilioolivares 1 day ago

Hey man, I’m also from Mexico but currently live in NY. This is pretty awesome. How did you manage to get traction with small businesses? Would love to chat if you have time, my email is emilioolivares, I use Google email.

reply by rsoto 1 day ago

Hey, Emilio!
Sure, I’ll send you an email, however, I’d like to keep the answer to your question on the public side, if you don’t mind.
It has been quite a ride to get traction, mostly the first clients signed up after talking to them about their issues with their invoices and expenses–once they’re interested, we begin the education process. The other sources are a mix of everything. One of our services is a platform in which our client’s vendors can upload invoices so they can manage them. We get some information on several businesses, both small and big so we can begin to offer our solution. This particular product might be the best source for viral growth, as one client can introduce 10 or 20 new users on our platform.
We also have a relatively successful side project on a related field [1], which has several hundred hits daily. There’s an ad there, there might be some optimization on both the ad and the landing, but we’re still trying to figure that out. Finally, our focus has been towards explaining the product, as there’s nothing like it on the market (actually there are, but they’re small and having the same difficulties we have). Once they sign up, our onboarding process is focused on one point: send your first invoice. As we saw many of the new signups not completing this step (or the previous 2), we set up an email communication strategy for each one of the steps, with our contact information in each email. I’ve blogged a bit [2] about it.

Now that we’re sure our product is helpful for the businesses, we just started promoting heavily with a sales force.

I hope that answered your question!
