I thought about posting this for a while, but then when seeing someone else here post something in the codegolf section, I figured I'd actually, well, post here. I'd also seen an IFMudder or two post, as well as several people from my past outside the IF community.
SO has been invaluable for me to learn Git and Python as well as some separate tricks in PERL I didn't know before. I know we had a SO type structure for IF but it never gained critical mass.
It really does feel like cheating with helping me know stuff, and the semi-stupid badges for voting, editing, etc. really appeal to me.
So who else participates? How much/how heavily? If you don't, I'd encourage you to. Just voting helps you feel like you're doing and learning stuff, and seeing that 500000+ people viewed the page with your question, or 2000 upvoted it, helps you feel you're not alone asking a potentially silly question. It's helped me ask a lot more.
