So far so good. In a smaller community I feel more responsible for contributing to discussions. Others seem to be engaging too with thoughtful comments (not just karma-farming inside jokes).

This is helped by the fact that new interesting threads are not immediately buried in heaps of new content, so you actually have time to think of an answer that someone might actually read and reply to. I realize that this is mostly a function of the current scale of the Fediverse and that the more it grows, the more it might just turn into Reddit.
