I think there is room for another social network. But I don't think it looks like X-except-for-not-some-bad-thing, because the people who complain about things like Reddit's API access are not many and don't have a clear use case -- I mean they want Reddit plus a tool someone else built not something different from Reddit (or Twitter that isn't Twitter, or Facebook that isn't Facebook). But most of what they want is Reddit, Facebook, and Twitter and so Reddit, Facebook, and Twitter provide most of what they want. And that's not even most people. Most people accept the tradeoffs and go on with life and get value out of the existing platforms. A new social network will expand the market. Make the pie bigger. Fill a different role. Let people do something they didn't know they wanted to do. It won't be capturing people who want different business models or moderation policies. Those are fringe people who have issues that they want catered to. The important question is not, "how are people using social media?" The important question is "how are people not using social media?" Good luck.
