Anyone tried a "conversation cafe"?

It’s reported as a trend, where coffee shops will post a meeting time for maybe every two weeks where strangers are invited to talk in small groups. Coordinators are supposed to be on hand to suggest starter topics and help people sort out, so that the news junkies and sports junkies find each other, etc.

Sports junkies hang out at coffee shops???

Anyhoo, sounds kinda cool. Until you get in a group with a loudmouth who won’t shut up. Like me, for instance.
