Sounds like a strawman to me. Who here has said anything about wanting nothing but positivity, or to be told how awesome they are? Even negativity can be combined with encouragement and support. And it doesn't really cost anymore to do that.
A. "Your idea is pretty bad. You suck. Kill yourself."
B. "Your idea is pretty bad; have you considered XXX? At any rate, best of luck to you!"
OK, to be fair, (B) cost a few more characters of typing for the pedants in the audience. But there's no significant extra cost involved with throwing a little encouragement and support someone's way.
Favilous: It looks like a bookmarking site. Solid site design and layout. Not too cluttered. I don't use bookmarking sites so I can't really comment on how it is different/better than other bookmarking sites.

ya... probably is. Thanks for the feedback. ;) Although, the OP pretty much says "I hate you all because all you ever say is mean things" so there is that.
