Why is my Lemmy experience feeling so lame? - Lemmy Today

I’ve subscribed to a plethora of communities that really interest me and actually have posts and discussions in them, but I have to go to the specific community to see this. My “Subscribed” feed only contains a few of the same posts that I’ve seen for weeks in Hot, the same posts from even longer ago in “Active”, posts from the same communities as the ones in “Hot” in New and no other communities, and pretty much only posts from the Meme’s community I unsubscribed from when sorted by “All”. I also see a majority of posts barely have upvotes or comments on them at all from the “bigger” communities. Is this just the growing pains of this site? Am I still doing lemmy wrong? Is it the instance I’ve chosen to join?

I have to sort by “New” because “Hot” is almost always broken. I get posts from two years ago :/ If I sort by “New” however, some of the posts are pretty… eh?
It was explained to me last week that the reason it does this is, the algorithm currently checks for interaction and if someone interacts with a 3 year old post it gets put in the pool. If I interact by upvoting the old post because I didn’t see the date, it gets put even more into the hot pool. This happens again and again to make posts come back from the dead. Apparently they’re working on adjusting this.
So, essentially it's 4chan's Bump system?
Seems like it, only old posts dont dissapear into the void, they stick around forever.
