add humor category
This pull request isn't ready to go yet until a "humor" category is added to instances.social. Issue opened: https://github.com/TheKinrar/mastodon-instances/issues/62.
Just as a quick check, though, does this seem like a reasonable category to add to joinmastodon.org? The idea is to have a category for instances like freedom.horse and wafflec.one.
Update: it's ready! there is now a
humor category on instances.social. :)
