Nostr is currently for hobbyists, like it should be at this stage. No need to rush or critique it.

Like Linux was in the early 1990s, first adopted by a fringe of supercomputer folks and those wanting an alternative to msft, Nostr is today for the bitcoin community and freedom advocates.

Today Linux is everywhere, for example Android.

Point being: we don't need to be disappointed, at all. This isnt a VC backed venture or anything. It will mature and progress on its own pace. And it will grow and succeed. Same as bitcoin.
