I've been asked to ride the Wave

I just got my invitation and I've sent out a couple of invitations. I put up a notice on Facebook soliciting interested friends and acquaintances. Will it be too hard to use without all of my existing contacts?

A great quote from Cory Doctorow's new book Makers:

Lots of people tried to play it safe. It didn’t make them assholes, even if it did make them ineffectual and useless.
