I used to be a lurker of r/C_programming where people would ask questions and get answers. It mostly consisted of students wanting to get a human answer to their problem.
I liked chiming in there and answering from time to time. Although you always had that one student who ordered to do the homework for them, there were some nice and helpful interactions in that subreddit.
Would people be interested in a community focused around helping each others in programming? Or would this very community do the job already?
Seconded the programming.dev instance! They’ve got communities for like every kind of programming, I’m moderating a Haxe community there. Right now it’s quiet enough that I think you’d be better off sending more traffic that way than making a new community on Beehaw, but I could be wrong.
