Now you can chat with your contacts in AOL Instant Messenger (AIM) account from Gmail. Google has just integrated AIM into GTalk. To sign into your AIM account, click the drop down menu under “Contacts” and select Sign into AIM.

Then your AIM buddies will show in your Gmail contacts list with a tiny AIM icon. I hope, not sure if it is possible, Gmail will include MSN and Yahoo Messenger access soon.
