If there's one thing Hacker News lacks, it's biting criticism and pessimism :P Kidding aside, I see your point. I guess it's important to distinguish between criticism and dismissal of an idea. "Dropbox is just rsync" seems like a dismissal, not a critical look at the validity of the idea. And Lily Allen turning down bitcoin? Well honestly I'm a little with her on that one. "Oh yeah can you perform and we'll pay you with a totally legit online currency we swear." Not exactly a great sell.
