Fret no more. There's a service called Trillian.
Trillian is a fully featured, stand-alone, skinnable chat client that supports AIM, ICQ, MSN, Yahoo Messenger, and IRC. It provides capabilities not possible with original network clients, while supporting standard features such as audio chat, file transfers, group chats, chat rooms, buddy icons, multiple simultaneous connections to the same network, server-side contact importing, typing notification, direct connection (AIM), proxy support, encrypted messaging (AIM/ICQ), SMS support, and privacy settings.
In other words, instead of opening up AIM, MSN, and Yahoo Messenger, all I open up is Trillian and it signs me on to all three services (now we just need to get them hooked up with Skype). Or I can sign on to just two of them. Or one. I *love* it. It doesn't take up a space on my taskbar, and on the rare occasion I have multiple chats going, it tabs them in one window instead of opening up a different window for each chat. Plus it doesn't suddenly scrap the webpage I was looking at or open another window for its homepage.
It might be old news to you, but it's new to me.
