I think part of fixing the problem of no-shows would be to not let members see who/how many people have said that they're going. If 25 people say they're going to show up, then it's not a big deal if I don't, right? Until half the people have the same idea. There will be more perceived social pressure to keep that commitment if people don't think they're just going to get lost in a crowd.
Oh jeez my worst nightmare might just be going to a Meetup without knowing how many people I should expect and ending up being the only one who showed up. If Meetup didn’t tell me how many people RSVP’d I’d never go to any of them.
