I think this is a problem that will be solved with time. The early users have a heavy slant toward a shared topic. That’s what pulled people in. It’s a bunch of builders who are passionate about the tech. The technology is still being built and refined. As it continues to improve, it will be more approachable to users who don’t want to figure out technical details. Lower friction for usage.

At the same time, creators from different communities are slowly finding their way here. They start posting here in addition to their other places #AlsoOnNostr, and it becomes more welcoming to new users.

You do raise many valid concerns, particularly the one about how difficult it is to find other communities. This is the kind of stuff that is part of the building and refinement process. Please keep speaking and sharing your viewpoint, it will help shape things.
