They definitely work hard to make the $19/month they charge you worth it for their customers.
One interesting aspect of Meetup's email strategy that the author doesn't mention (because it's only tangentially related): Meetup.com doesn't give organizers access to their community members' email addresses. The only way for the organizer to contact the community is through Meetup - this creates lock-in to the service (and much frustration). It's probably a wise business policy for Meetup, but becomes a point of contention for the organizers of larger groups.
On a related note, Meetup seems to succeed in spite of itself. They recent released sweeping changes to the design & functionality of the site without notifying organizers, resulting it this epic thread of discontent: http://www.meetup.com/boards/thread/10376961/0/
I think there's a great opportunity to create a service like Meetup that addresses some of these downfalls. If anyone is interested in building something like that, let me know: joe (AT) svnewtech [DOT] com
Why do I keep going back? Because a local group I meet outside of meetup has their mailing list, schedule, or something on their meetup site and I need to have an account to take part.
Though honestly I'm about to delete my account and will likely never re-create it.
I ultimately had to rejoin in order to attend certain events but I still lost trust for the service.
The thing I don't like is that the feature they've been seem to be copied from Facebook rather than being specific to Meetup - especially, it would be nice to have to calendar and event oriented and less chat-oriented (especially, it's annoying getting extra-info about event I already decided not to go to).
But the valued offered by Meetup is in many ways better than the Facebook equation; Meet people you don't already know face-to-face rather than chatting online with people you've known forever anyway.
Though it is harder to scale, I think there is a lot of potential in this go local strategy.
