There's an interesting article on BetaNews about MS and Yahoo announcing that as of next year they are going to merge their 2 currently disparate networks, so users of MSN will see their friends who use Yahoo online and vice-versa. It seems this move is partly to combat AOL's dominance, but also to combat Skype and Google Talk.
Personally I think they should have done this years ago. VoIP (although not necessarily through Skype) will, I believe, soon become even more popular than IM. Why type when you can talk?
