I think a chat service would be a large item that not many people would partake in... Which would require a lot of work to maintain in the core code
I'm with Giz on this one. I've tried chat rooms and they were all largely ignored. The only time I could see them as being needed was if you had numerous people on at one time that knew each other. But, I know I'll not use one again.
