I'm personally not enthusiastic about real-time synchronous messaging (for the already mentioned reason that it does not produced structured, reusable content), and I think it would be nice to gather the opinion of the people that populate the IRC channel today.
(Plus
gitter.im is a proprietary, for-profit platform, meh.)
Yotam, would you be willing to go on IRC and have a chat about a
gitter.im room with the chan, to see what they think?
It would also be nice to have a gitter/IRC bridge (I hear that this exists). Who would be volunteering to take care of the gitter stuff and make sure that the bridge works properly?
