I'm only answering because I know the answer, not because I recommend/endorse this room. I regard it as for entertainment only and do not think it is an efficient use of time for a professional trader.
It is not my intent to disparage that chat room but this is a forum targeting professional traders and that is my opinion. I sometimes take a peak in that room during the trading day (its free and publicy accessable) as I also flip around on my TV to non financial channels (I don't trade news anyway).
