Ask HN: Is there a directory for failed startups?

Most of the time everyone talks about startups that made it and those that fail are forgotten, but is there a website where I can see more info about failed startups? There are a lot of talks on HN about failed startups but again most of them are forgotten and fade away.

I am thinking of building such a directory where the founder can post his story and lesson learned. Many blog about it, many don't even bother and move on but I think it is a valuable experience to share...I really think startup failure is a big topic and it is or it should be part of the Lean Methodology just before the pivoting...learn from mistakes...there should be tools to learn from mistakes...every aspect of the failure should be analyzed. Some people do this, but I think everyone who pivots should really analyze the failure just as much as analyzing the potential market.

So plz provide links if there is such a directory or tools for analyzing startup failure, if not I think I will make such a place as a side project.What do you think?
