The way I used Twitter was by aggresively muting, blocking & managing the interests functionality through the years until I pruned my home page to mostly show me meaningful discussion about videogames (and a bit of other media), some relevant news, including a good balance of AAA and indie stuff as well as a a balance of mainstream (mostly from US and Japan videogame industries) and diverse stuff (ie from other countries). I had industry people, interesting youtubers (more essay-types than gameplay-types), socially progressive viewpoints, diversity, a bit of art, a bit of lore, etc.

Are there good instances focused on that? I know I can see stuff from any instance but AFAIK some are better to set up camp because of their admins, their defederations and also because it's a bit easier to find new interesting accounts to follow from within the instance.

Which do you recommend?

EDIT: I do know there's no algorithm in Mastodon like in Twitter so I'll only see whoever I follow. Just wanted to clarify before someone took the work to explain all that. I just want to replicate the kind of feed I had on Twitter, just that this time it'll be 100% from following accounts rather than a mix.
