alt Hacker News> Every great project was once called a bad idea
What a concise explanation of 'survivor bias'. Well done!
The problem is that every bad idea had someone behind it saying it was a great project, and the number of such bad ideas vastly outnumbers the actual success stories. To be fair, if the point is to say "Don't listen to the haters", that remains a good point.
The issue here is that the people commenting on whether something is a good or bad idea usually don't have the necessary insight to give useful comments either way. But with certain trendy topics, many people still feel the need to express their shallow opinions. That is especially true on HN, because many like-minded people will chime in, upvote and increase visibility as long as they themselves feel validated, irrespective of whether what was said is true or not.
In fact I'd love to see an inverse to this list. I.e. shit people celebrated here that failed miserably. Although failure as a business can have many reasons and must not necessarily be due to the core business idea. It's probably much harder to get this data than searching early HN threads for high value IPOs. You'd have to search for popular threads and then track down the companies and find out what happened eventually.
