To me, this just demonstrates the problems that arise when you say you're trying to tackle this huge gigantic problem. There's a ton of building hype, and then people are disappointed/scornful when you can't deliver. It reminds me a bit of the Thiel Fellowship.

Maybe this YC class is just a result of many lessons learned. It does seem the problems they tackle are, for lack of a better word, lame, but that doesn't mean they can't grow into something really big.

I guess time will tell, but best of luck to Makr.io. My only wish is that they share everything they must have learned through the process of Diaspora.
