I think the general impression is that chat rooms are informal, temporary, and impossible to regulate.
This site is a living, growing repository for firearm information and bad jokes. It would not really benefit anyone here if the medium was a real-time chat that had no archive feature.
It also seems to invite more rudeness and flaming when the stuff you post today disappears in two days. As it is now, you can do a search and read every stupid uninformed thing I have ever posted.
Kinda keeps me in check.
Or, I could be completely wrong. Again.
