Learned a new term, didn't know what a troll box was and had to search for it. Now I know it's the chat window I really liked on Coingrounds, the short-lived PTS exchange. I loved it. It was a lot of fun and very informative watching the real time commentary on the trading by different types of stakeholders, along with my occasional question getting quick answers.
AFAIK it really got popularity from btc-e - speaking of masses control done via manipulators there...
it's people yelling buy or sell like they would on the floor of a normal exchange, i actually found it really helpful to trading to see the sentiment.
