We're a bit worried about our "the social conference directory" tagline, since we've had a few people think the site is only for social media conferences.
Lots of people are using Lanyrd for group meetings, social events, and all sorts of things that aren't conferences (eg http://lanyrd.com/2010/brightonpy-october/skgp/ ). It might be worth rethinking the tagline to make it more friendly to this kind of thing - assuming it's something you want to encourage.
That's very true, but what are these "things"? They aren't just general "events" a la Plancast. "meetup" has been taken by another brand in the same space. Meeting sounds too... work like :-)
