Not so much programming tutorials, but there's www.growthhackers.com for marketing article sharing. It's divided into categories (Paid, SEO, Content, etc.) though the content of the posted links usually isn't too great. I'm not sure what potential users would be looking for? Quick tutorials for the "Gee, I've always wanted to try that and have an hour" crowd or something more in depth that someone would come specifically looking for. If it's the latter, a directory supported by a voting system might be a little better. Just my $.02
