Was very vibrant 12-18 months ago.  We used to have an account called "Nostr Report" that used to show case 3-6 (sometimes more) innovations every day.  

Now it's quite hard to find even one.  I normally trawl through this site here and pop anything interesting on r nostr.  But its increasingly difficult to find interesting stuff.  Other projects invest in their devX and it pays off.  Nostr didnt.  Though Nostr still has quite a few payroll devs thanks to the amazing generosity of jack.
