It comes up for me in all my browsers except Chrome, where it's blocked by an add-on. People generally use it to help each other out. They post links on how to do stuff, neighbor requests, work requests, bonuses and ingredient requests. But mostly they just shoot the breeze and chat about whatever. I occasionally post my bonuses there if I think it's something people actually want, but I don't hang out there much myself. It seems the people who do already know one another because they also work one another's facilities. For the most part, in so far as I've observed, they seem like a nice group of players.
