It seems like there's a lot of friction involved with connecting to the wider ecosystem. You can sign up to a smaller instance but then federating with others may be problematic. Or you can sign up to a larger one, but it seems like network effects might eventually have things evolve to just a few massive instances, somewhat defeating the purpose of decentralization. Or you can host your own, which would be a technical hurdle for many and come with its own burdens.
