a proposal
This is a great first shot. Do you want to start a task force and articulate these principles there? We can call it the Volunteer Task Force or something similar. I'll jump in there.
Starting a task force is a good idea. Not sure what I'd need to do there beyond just making one page. It should probably have a more well-defined scope than just volunteers in general, otherwise it's likely to retread over the same themes as the community health task force. I'd rather spend more time trying to get to the implementation of an idea than to spend another few months discussing ideas. I think that's what Wikimedia needs now.
The theory behind the current structure is that, if there's a concrete idea, someone should write it up as a Proposal, and people can self-organize around that. If some thinking among multiple people is necessary to generate a Proposal or other useful documents -- a statement of principles, for example -- than those people should create a Task Force, and these documents should be articulated as deliverables.
In this case, you've already written a concrete proposal about how to start doing this work. So maybe we should start there? If yes, then I've already signed up on that proposal, and I'm willing to go with it. Please be patient with me, though. Lots of discussion going on right now around the Strategic Plan that I need to participate in over the next few weeks. (Hope you can help with that too.)
