communication.  Much of this is simply the nature of software.

It has nothing to do with software and everything to do
with architecture. IM networks have less problems because
all the participants share a relationship with the IM
service providers.

It *is* interesting that the diversity of disconnected email services was
viewed 
as a basic problem to solve, whereas most of the Internet user community does
not seem to feel the same pressure to unify IM.

Hmmm.  Maybe IM satisfies a different set of needs than does email.  So we had
better be a bit cautious about trying to generalize implications between them.
