The idea of collaboratively editing a session transcript and backchanneling in real-time actually hadn't occurred to me. Genius.<p>I see two major flaws: provision of reliable Internet access at conferences is still Not Done Well; and the drawbacks of the current Wave UI implementation do not really encourage this sort of thing. (Oh, and trolling, yeah.)<p>I mean, we could have collaborative transcript wikis at conferences already, right? Add Twitter and what value does Wave really provide, especially given the discoverability problem? Why <i>don't</i> we have transcript wikis? Perhaps that is something to address first.<p>I'd like to see (and wish I had time to create) a universal backchannel solution and this is certainly one platform that could well be worked in, but you gotta get over that offline barrier somehow.
