I think the expression "kind of a big deal" is really funny. It comes from the movie Anchorman, where the gregarious newscaster introduces himself as "I'm kind of a big deal."
Folks on MySpace and Facebook use the expression as a way to say "I think this important, maybe you will too" as opposed to "I will force you to recognize the inherent importance of this." At least I think that's what it signifies; I mean, it's a joke and all.
Any rate, I think this event will be cool, fun, and important. I'm going, and I hope you will too:
