A good example is Shakr, a "social online hangout" which won Disrupt SF in 2011 [1] and raised $15M immediately after. Robert Scoble said it would become a $100M company.
Huh; it's probably a bad sign that I see a little too much of my own startup's pitch in that description.
(Then again, I usually describe my startup as "a group chat/collaboration tool that has learned from the reasons people prefer MMOs to IRC." Framed that way, it doesn't sound nearly so priggish--but I don't decide how it's framed, the public does. Sort of makes me worry.)
Yeah...
