When I first read the comment I read it as overly confrontational and I didn't really like it(esp. after reading the thread on flagging.) I didn't read it as feedback because it wasn't a Rate my startup submission but a techcrunch post so it felt like a tl;dr comment. Viewing it as a constructive feedback comment makes it seem less snarky and less confrontational.
Ah, sorry - my intent wasn't to be snarky or confrontational. I automatically switched to review mode after reading that it's a YC startup, since I figured the founders would be seeing this thread.
