I am logged into Flockstr now. I guess it is looking pretty good, if they can just finish building it. Calendars seems to be the nearest equivalent of Meetup groups.

Search doesn't seem to work yet. e.g. I can see an event in Phoenix, AZ under Explore, but I can't search & find that event. Which begs the question of how I am supposed to find events near me, or have other locals find my events.

I guess it is what we have, and I will definitely keep checking back.
