"Maturity" can be defined many ways (including age, temperament, or depth of skillset).

I doubt that there's any magical hiding place that differs from other developer hangouts. It's not like we are all out there despondently pining for new comp.lang.c articles while chasing those damn neighbor kids off our lawns.

Perhaps specifying a more specific metric (languages, environments, databases, etc.) could facilitate your search?
