As a new user I'll give my thoughts, other's mileage may vary.

Personally I'm interested in converting a mini mill so the bits I'm interested in are the software and hardware for the stepper drives, beyond that anything about the bed/gantry type machines are not that relevant for me and that's what the main focus of the forum is.

I also think a lot of people sign up as they like the idea of having a CNC machine but when it comes down to it don't have the time/money/motivation to actually do it.
