Filtering by New seems to be the best way to view Lemmy.
Over the last few days, it seems that filtering by Hot or Active just makes me see the same posts I've seen over the last few days (stealing memes meme and $4k fridge).
Filtering by New on Lemmy, however, is not the toxic filth that Reddit is, and generally gets the job done.
Unless I am doing something wrong, Hot and Active seem to not update enough / hide what I've already seen. I am doing my Subscribed, about 20 subs.
This has been the same experience for me, Active/Hot shows posts from Monday because they're still gaining comments but New shows genuinely new posts. I think the algorithm may simply not be tuned for tens of thousands of users
top.day isn't bad if you want some more developed posts with lively comment sections, and I believe it's guaranteed to rotate every 24h. But yeah, hot is broken on a lot of servers right now (should be fixed in v0.18.0), and active isn't aging out some of the monster posts that people keep reviving with new comments.
I think you have to tap on the post and then the website would then know you’ve read the post and then it hides it. I don’t think Lemmy would hide it after voting on it and not expanding on the post you’ve interacted with.
