Meetup

One thing Shirky kind of overlooks is the shift in most of these platforms to at least a certain level of alienation and paranoia. I don't know the whole history of Meetup, but look where things are by 2005.

This was part of a switch from free to paid. I think Skirky sould say this is another example of changing the bargain. Or violating it.

Then there was The Purge.
