The thing I keep thinking is that I want to have social software built on a co-operative model (like a food co-op): you all pay some nominal membership fee (could you fund servers and developers on $5/year/user?), and the software would then be developed to fit the agreed-upon needs of the community, without dark patterns or behavior modification projects, openly, and with some kind of community governance (which need not be exclusive of technical leadership).

Obviously this would probably never get the global reach of a no-fee Facebook, but I would use something like this in a second, many of my friends would too, and I sometimes daydream about what I would need to do to get it off the ground.
