This suggestion has been brought up a few times. I think we have all come to realize that it would be nearly impossible to moderate. As I and Carlie already spend a lot of time trying to keep the site free of spam with set posts, a chat would be horrible.
I still don't understand what you mean about the people here. There are 32,000 members. Spamming is a central issue here. There is no bright side to a chat, I'm sorry to say. The comment sections and forums are perfectly adequate. A chatroom is only begging for spamming in inappropriate online behavior and there are not enough moderators to manage it properly.
