I like that the admins have decided on quality over quantity when it comes to communities. For example, there is only one gaming community instead of breaking everyone into several smaller subsets. It increases interaction and exposes you to other subtopics that might spark your interest.
I hope moving forward they continue with this approach!
Yeah, a big problem when starting new forums is breaking them into too many categories that eventually go stagnant. A lot of forums would do well just to start with a single, general category, which !chat basically is.
