I would really like the ability to create my own algorithm. For example, I follow communities for my local sportsball team and memes. Memes, I really just want to see what’s “hot” for the last day but my sportsball I want to see everything posted for the last week.
And the real dream would be to tweak this algorithm across fediverse services.
My thought (but may be wrong) is to use All and block those I don’t want. This (I assume) would allow me to see any new areas. It’s tons more work but I think ultimately it will expand my areas of interest.
