Yo admins! In preparation for a better joinmastodon.org sign-up wizard, https://instances.social directory now lets you set a category for your instance, in the admin area.
The categories are: art, music, books, activism, sports, games, tech, academia. It's ok to not have a category, too, like for example octodon.social is just a general purpose instance. But if yours is themed, you better categorize it.
If you think a crucial category is missing, tag @TheKinrar
@Gargron Oh that's so great, I really missed that feature when I was looking for an instance !
@TheKinrar would it be possible to add a "LGBT" category ? That's clearly one I would be looking for myself.
@Gargron @myrrhashad and instances still have the possibility to add a topic, which you already can search by on joinmastodon.org
but only one instance is returned 
@TheKinrar @Gargron Makes me wonder if instances are aware of the topic-stuff...
@Gargron @TheKinrar Yes, I get what you're saying. Clearly I would be looking more for "LGBT-friendly" than "LGBT activism", but then it's not really a category by itself.
@myrrhashad @TheKinrar I would like to accomplish displaying *only* LGBT-friendly instances on joinmastodon.org, but I'm not sure how to do the vetting yet.
@Gargron It's nice to know you're thinking about this :)
@TheKinrar
@myrrhashad @TheKinrar I think this needs to be approached carefully. Categorizing instances by identities may make a bad impression. In terms of LGBT activism, we've got "activism".
