Six months on, here's what I've learned from Meetup:
*It may well be going the way of MySpace or Friendster at this point. There's just less activity than there used to be. I may be wrong and they may be able to turn it around, but I suspect the sun is setting on Meetup.

I think the system is set up to favor a kind of dilettante-ism: you try the nonduality group, the Zen group, the crystal-gazing group. I suspect that people who are looking for Buddhism specifically have other ways of finding it, such as DharmaWeb or DharmaWheel. Or google.
