I know the Arduino section was not successful but I see a lot of STM32 questions come by. I count ~30 in Electrical and ~60 on stack exchange in the last month. I have no idea at what frequency it makes sense.

I'd say it doesn't make sense creating a site for just that microcontroller, all questions fit here (if good).
It's a useful tag though, and it's worth checking that all questions have it.
