@Natanox Hard agree.

Oddly, the only fedi environment I encounter this with (if you exclude the point where you see stuff you've seen before, as with Mastodon) is Lemmy, ie. alternative Reddit.

Its clients (I use Voyager) have the ability to hide posts you've already seen, so you essentially get only "new stuff" and 1+ year old posts.

Sadly, I've not found a way to get it to treat posts older than X months/years as "read", but feature requests are a thing.
