Right now people just pick relays kinda randomly.  A lot of the time they pick relays that are very specialized and just don't work for normal nostr things.

This "test" button will tell you if a relay works, so you only pick relays that work instead of picking broken or specialized relays by accident.

And what are you drinking? 

 Good whiskey,
and yeah, thanks. you're got my attention. I'm being retarded while my leverage hits crutical.
