From paidcontent.org:

…this March, as Jon Fine reported Friday, when AOL begins in earnest to roll out new features. (No comment from AOL.) AOL already has expanded AIM’s mission from an instant communication tool built around buddy lists by using it to deliver advertising and market AOL services. Now the Time Warner unit is pushing ahead with the extension of AIM in a way that will intersect with the content side from the user perspective. Look for the new effort to include personal web pages integrated with AIM in a variety of ways.

Even better, they’ve decided to embrace open source development and have already released an alpha toolkit that you can play with.
