I have been looking into adding a place for user interaction for some time and as we were looking for another challenge we have decided to go with nodebb.
The reasons for this is simple: nodejs and mongo db.
I have played around a bit with mongo for the uNoGS site but never really used it in anger. As nodebb uses this extensively I figured I could learn a lot from the way they interact with it.
To be honest, I'm not sure what to think of nodejs but there seems to be a lot of buzz around it at the moment and I figured I better find out why.
Anyway, as I hack around I will add any insights, tips or tricks here.
