I just have to say that after a couple of weeks trying out Trillian I'm very impressed. All of my personal chat and email in one convenient window (except gmail). It really is "The Swiss Army Knife of Instant Messaging." And I'm using the free version. Give those hoopy Cerulean froods a pat on the back. They really know where their towels are.
*I've noticed a lot of people coming here on a search for "hyper-intelligent shade of the color blue" and I don't explain much about it here. I assume you know that this is a reference to The Hitchhiker's books by Douglas Adams. If you want some Guide kitsch, they have a nice supply over at CafePress.*
7/15/07 Update: You can also check out the entry for the Hooloovoo on Wikipedia. If you would like to leave a comment to tell me WHY you were searching on the Hooloovoo (the hyper-intelligent shade of the color blue) it will help me put the info here that you and others will want to find. I get about five hits per week on that search phrase. If you can't comment on blogger you can also email me at email@example.com.
