So apparently http://rblind.com has been created as a lemmy instance by some refugees from r/blind, which is awesome. There is a lot of discussion already in the main sublemmy, so
!main@rblind.com
or, alternatively
http://rblind.com/c/main
might be interesting to anyone who reads this. I think it's very exciting to have a blindness focused instance, so we can have subcommunities within the context of blindness.
I also want to mention that I originally created !blind@lemmy.world because I wanted to discuss some screen reader issues, and there was no other place at the time. If the r/blind mods are interested in having mod access to this community, just give me a heads up.
