Yahoo Messenger has shut out Trillian. I had read not long ago that this was going to happen, and I learned first hand this morning that Trillian had finally been given the boot. The only reason I use a client like Trillian is that the greedy scumbags in the IM world refuse to pursue interoperability, and I have friends on all of the different IM services. If I really want to run ICQ, MSN Messenger, AIM, and Yahoo Messenger on my machine at all times, I’m going to need to buy more RAM.
