Here’s an interesting program - IM Smarter

IM Smarter is a new kind of instant messaging enhancement. IM Smarter empowers all of the major messaging services with a rapidly expanding set of cool, new features. It’s not a “bot”. It’s not a plugin for AIM. It’s not a program that you run instead of your existing IM client. Using IM Smarter can be understood as hiring a secretary for your IM; IM Smarter, like a secretary, sits between you and the rest of the world and helps you manage your messages. Imagine having one place you can search and visualize your instant message chats with anyone you’ve chatted with using any of the major IM networks. Imagine being able to update your blog as easily as sending an IM, and getting an IM whenever any of your buddies update their blogs. IM Smarter keeps you in the loop with things that you told it to remember and things you told it to keep an eye out for.

I haven’t tried it out yet, and I don’t know if it works with GAIM or Trillian, but thought I’d pass it along anyway.
