I'm at a point in my life (personal bandwidth hovering near 0%) where I'm not getting involved in anything unless I have not just a good reason ("this is a noble agenda; somebody should do something about it, and hey, I guess I'm a somebody"), but a damned specific reason ("I have unique capabilities which can help this specific initiative in this specific way").

Anyhow, in this particular domain, I'm pretty sure there are people who could be MUCH more useful contributors than I. I'd love to forward the "manifesto" to them -- except I know that they're in the same position as me: essentially zero bandwidth. Any new project they get involved with means dropping something else that's currently on their plate, and is presumably important. They're not going to do that on a lark. They'll need need a damned good reason to participate, before deciding to spend time on something new.

To be honest, ANY real power-players will be in this position. They don't have free time on their hands; they won't just join up in the vague hope that maybe it'll be a place where things can happen. You will need power-players on-side, and without a much more specific proposition, you're not going to get them.

But I'm glad you've joined. Job no. 1: that manifesto needs to do a lot more manifesting before it's fit for purpose!
