Instead of categorized instances (where communities are related to each other's interests) (but I have seen people who don't like the idea stil it's ok), I have another idea of an "Admin's Choice/regional/neighborhood" feed aside from my "subscribed", "local" and "all".
An "admin's choice" feed is where admins of an instance can promote approved posts/communities outside their governing instance upon their interests/preference, as an addition to the local feed, but it does not include all other posts/communities not in theirs. For better clarification:
"Subscribed": Communities/Posts (whether within or outside home instance) that I subscribe.
"Local": Communities/Posts that the home instance has.
"Admin's Choice": Communities/Posts that the home instance has + the outside communities/posts that the admins want to include.
"All": All Communities/Posts (whatever federated instances have, whether within or beyond the homes's preference) as long as the home instance connects to.
I realize when I browse other instance through their URL literally, every instance has own somewhat taste/personality of communities and posts done by the users joined in the instance. That's why I pop another idea.
Buts:
Q1: "Why not subscribe to the community?"
A1: If I subscribed a very specific community just for a single and immediate post or event, my "subscribed" feed will provide also other unnecessary and complicated (somewhat critical analysis) posts from that community, which I will never look up to. I just want posts of my particular interest in case of somewhat significance.
a1: For an example: I'm a (assuming) music lover, I just want to hear about a music artist concerts but I don't want to hear moreover about other analysis/extra gossips about the music artist as I just wondering going his concert just to listen and jam.
Q2:... My brain's timed up. I can't think anymore contras further, so anyways. My bad if many.
Very sorry for not enough understood (and may never mind this idea of mine) as I hardly describe what I really mean from my mind to suggest.
May the odd votes be in your favor.
not yet right now,
hilarious by those outputs.
But still, sooner maybe, as long as AI keeps learning and improving and advancing, it may come true sadly.
