I think nostr is great because its pretty Normy friendly (and primal is very easy to use, as are many other apps).
Its important that new apps and programs can be easily distributed to the general public as they will support something when they see the need, and lately enough people seem to be looking for alternatives.
Too often "alternative" tech is way beyond what a normal person could get into using, and that's a shame. We'll never replace the legacy tech giants if we can't bring Joe public on board. I know as I am one of them.
