There are a lot of traffic exchanges which now have a side bar chat. You can surf for traffic while chatting with other members of the exchange. I have learned a lot of priceless information by watching, listening, and chatting with others.
I have been a member of Thumbvu for over a year. It is a unique traffic exchange where you can actually pick which site you view from 3 different "thumbnails". (Thus the name) A few months ago the owner, John Guanzon, added the chat feature to his site. I have always enjoyed surfing Thumbvu but now it is an even better. I can get credits for my sites while chatting with other Thumbvu members. It's called Social Networking and it Works!
If you are not a member of Thumbvu, I urge you to try it. You can even join for free.
