Okay, well, I don't think real time chat is very useful for serious discussion. Maybe its a generational thing. But I still prefer email and forums because I can take the time to reflect on what I'm reading, and to think carefully about what I'm writing. For real time communication, I prefer it to be face to face. About the only time I use chat is when it is available as an alternative to the phone for online help and support for products or services I have purchased.
