I run !gameart@sopuli.xyz for people who like video games and neat art.

You should also make a point of checking the sidebars of communities, sometimes they link to a couple other relevant ones you might like. I always do.

If you’re a weeb like me, come on down to the ani.social instance. Lots of communities, and again the sidebars of many link to others you might like, even off that instance.

If not, you could consider doing the opposite and blocking the instance in order to cut out a lot of the anime content from your feed, since it’s not your deal.

I tend to find stuff by hopping over to ALL now and then, but my sublist is now so big I usually stick to my subscribed feed.

I advice that it gets a lot nicer to scroll through ALL to find stuff, if you don’t avoid blocking communities and instances you aren’t interested in engaging with. That way the list of content gets shorter and easier to browse in terms of discovery.
