I don't know if this is true, but it should be a good (but scary) thing. The rumor is that we will be hearing about a Yahoo! and Microsoft instant messenger deal soon. The deal will allow for Yahoo! Messenger users to communicate with MSN Messenger users seamlessly. That, I think is a good thing. Hopefully, it will be a push for AOL to open up their AOL IM and ICQ clients also. And everyone thought it would be Google who would be the one driving IM clients to become open. Not. Update: The news is true. Yahoo! Messenger and MSN Messenger will sport interoperability soon.
