I call this set of functions "context assembly," a phrase I picked up from Groove co-founder Jack Ozzie. When collaboration devolves to the common denominator of e-mail, every participant has to weave context around an otherwise chaotic stream of messages, and there's no canonical view. Context assembly in disposable shared spaces is the essence of Groove, and in that sense TimeDance was very Groove-like.
Unlike Groove, though, TimeDance had universal reach. I have never encountered a diverse group whose members were all willing and able to use Groove. Today, its entry barrier remains about where it was five years ago. For a Web-based application like TimeDance, though, the barrier is now even lower than it once was.
