That's really great! Primal is just one of the many clients of Nostr which is what all of this is running on, I use one called amethyst.

There are many incredible builders on Nostr, and maybe part of it is perspective (I've been here over 2 years) but the amount of people overall using it seem to be declining as a whole, which is really sad since it is an open protocol so nobody can be silenced.
