I'm super excited about most of these ideas. I'm not so jazzed on armbands (both because it conjures up images of fascism and because it's easy for a bunch of schmucks to put on armbands and do something crappy) or buttons (because, like the peace sign, it's so easy to sell to the point that it becomes meaningless).
I like the idea of the (non-branded) free hot cocoa/consensus machine, but I worry that it'll take business away from the folks trying to make an honest living as cart vendors. BUT I do like the idea of there being some kind of kiosk that displays in the park (and linked to the web) what the proposals on the table for the GA will be. That would be super useful.
Awesome, and many thanks to Ben and Jerry.
