This is the somewhat accurate parts. A lot of NIP11 documents are scuffed... I crawled about 8000 relays online and any implementations that had a count of 10 or less were marked as other. rnostr/rnostr is only running on 12 for instance so it made the cut. There's a bunch running some weird version of something or their document is scuffed and I have other stuff to write before parsing this list more accurately.  

 Here's the full list if you're interested.

 Thanks for the full data. I mostly wanted to links to all the implementations 😀 
I also wanted to see if you had managed to find the relay I'm running 

 Did I find it?  

 Yup, although not going to tell you what one it is. :)
but ill give you a hint, it supports NIP-50 

 It's cool that I found it though! 

 One day I may try to group forks with the original implementation and qualify how many forks are running. As you can see... a lot of people have crummy NIP11 documents.
