Livecoding.tv (http://www.livecoding.tv/) has been an invaluable resource for me. At any given time of the day you'll find between 2 and 10 people working on coding projects, about half of which are game programming. The skill levels range from amateur to the occasional industry professional.
Hope this helps!
Thanks for this! I've been watching the Twitch streams but this seems much closer to what I'm looking for.
