Who's Making Noise #edtech

Always in search of a solid backchannel that is not only free, but open to unlimited users with an automated archiving feature BackNoise seems to have some real promise.  I haven't had a chance to use it yet, but the next conference I help to organize or attend you can bet I'll be giving BackNoise  a try.  P.S. Sorry for the hour of the post, passed out early last night after playing 27 holes of golf in the heat (up early to go at it again!)
