I don't think it has to be organized by YC at all - this is more about Boston/other city based networking than it is about. Jessica/Paul/YCombinator are busy enough as it is - but that's no reason why there shouldn't be a Boston meetup.

I currently live in Boston close to the Mass Ave bridge, but spend a decent amount of time roaming coffeeshops in both Boston and Cambridge.

I'd propose a meetup this Thursday (the 3rd) evening or Sunday (the 6th) evening either at Diesal Cafe in Sommerville (my favorite coffeeshop to hack in http://www.diesel-cafe.com/ accessible via the T), or the Espresso Royale on comm ave.

I'll bring my cofounder, and maybe 1 or 2 friends if anyone's around and interested.
