Just watched "Building Open Source Communities"
A superb talk by @ashfurrow
http://www.ustream.tv/recorded/102858222
It's not just about #OpenSource, but also the realities of #programming, concerns managers might have, and the issue of reaching people with different points of view
There are a lot of myths dispelled, great communication strategies, and it's presented in a very approachable way
Even if you're not technical, there's a lot of very useful info here on building communities
