I had the honour of hosting my good friends from Gamesatwork.biz for a BCS animation and games event to hear about how they have managed to create compelling content in a weekly podcast for what is not approaching 400 episodes! The official BCS event link page and links to everything else about the BCS is here but I have added the youtube directly. Its very free form, not scripted and was a entertaining to be the interviewer, especially as I know Michael, Michael and Andy just know what to say and when to say it.
As the guys explain a lot of the content is based on us all sending them things we are spotting or are busy doing and enjoying. All the podcasts episodes have their own show notes and links so after watching this go check those out and see the sort of thing they do, or vice versa and then start sharing stuff with them, the more the merrier. Also if you are in tech, check out the BCS as a professional org.
