I think I've covered my approaches to communication fairly well in my platform and in previous messages already.
I agree with you that fixer teams/delegations--targeted agreements between the project and a group of people working on a task--can be valuable tools. I also agree that the Bits from the DPL can be used as a valuable tool to let people know about discussions and where they are going on. I'll note that Misc Developer News can also serve that purpose and is a great resource for learning about what's going on in the project. I remember back when I joined the project DWN was one of the things I looked forward to with eagerness; it did a great job of helping me feel involved. I think my goal would be to let people know about where discussions are happening and help them know how to get involved. I'm not really big on creating a lot of polling of people who haven't been involved in the discussion. I've talked about using GRs as a tool, and I guess that's a kind of polling, but in many cases focusing a discussion on those who are interested enough to follow is valuable. I think that's fine so long as we do a good job of letting people know where the discussions are and how to follow in a timely manner.
