my two cents on RockMelt: why would I change browser (lots of work) for an experience. Is it 10x better at sharing or keeping me informed than my previous tools? I doubt it. (eg: j.mp bookmarklet is awesome, everyone uses tweetdeck, etc) (I am somewhat biased because I run a vaguely similar (but very different implementation) service: http://readness.com http://readness.com)
