Just my two cents here, maybe it's worth thinking of offering a more loose relation to specific fields for gittip users instead of projects/corporations, which isn't related to being compensated for being in that field. Something like the tag system on Stack Overflow, for example. Considering the broad scope you mention the platform could have in the future, it could look like this: upon sign-up, a musician adds tags to his profile, #music and #acoustic, a programmer adds #programming, #python and #opensource. That way you let your users build your categories, and your users get a nice filter for their interests, and as you mention in the side note, companies can get ad space by donating in the fields they care about. (I decided to give feedback here, since the issue is more about projects than communities, and I don't want to mess up the issue content.) Edit: I forgot to address the issue of people tagging themselves with a specific project. Maybe it's me, but gittip seems to be oriented around people, which is why I find the projects aspect confusing. I think a much simpler solution is currently in place (and maybe should be encouraged for this case in the future), where companies/teams/projects can sign up with a single account, and people can decide to donate to that account, and the companies/teams/projects solve the money split internally. I know you've done a lot of thinking on the projects aspect, and there's been a lively debate on the issue, but personally, it seems as it adds a lot of complexity to the system, with relatively little benefit.
