I get that you say that you want this to be donation-driven, but people aren't going to donate to a social media platform unless it represents a community that is valuable to the people who are a part of it. Wikipedia receives donations because hosting the world's largest repository of community-driven information is valuable to all kinds of people. And governments probably won't want to fund a social media site unless they get some kind of access to the data behind it

It would be nice to have more enthusiast-run online forums that focused around building communities rather than corporate social media sites that are focused on trying to become the next big thing
