It's a whole new world of instant messaging out there. John just pointed me to something I haven't seen -
Trillian, a multi-protocol IM client. Very cool stuff. Trillian has a buddy (no pun intended) on Linux -
EveryBuddy.
IM is an interesting beast. There are three real serious system players: Microsoft, AOL, and Jabber. The interface is locked up by Microsoft with Messenger and AOL with AIM. However, what will happen when Microsoft and AOL figure out they can charge a toll for the messages constantly running across their networks the same way Vodafone and NTT DoCoMo have done with SMS? It will be like the email revolution. Businesses will pull IM into the coporation. The only way that can do that is by using Jabber or setting up Microsoft IM for Exchange. Jabber is much more straight forward and it's free, at least for the open source version. I'm sure Microsoft will put a toll on IM for Exchange when they start toll collecting on a per message basis.
