And it beat out Trello too. Something that (at least for my circle) I would argue really was disruptive.

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.)
