Security vs. Usability.
Aim has buddy icons, a profile, away messages, and an easy install. Everyone uses it and everyone is familiar with it. "What's your screen name?" only means one client right now. If we encourage an IM revolution, people would be afraid of having 6 clients for each protocol trying to duke it out.
I can see it now:Quote:
"I think you should use silc."
"Can I keep my buddy icon?"
"No, but your messages can't be intercepted and your client is less likely to be exploited"
"But my buddy icon says Diva on it... :("
