Why is the feed algorithm so horrendously bad on Lemmy? I keep seeing the same posts I had previously seen/interacted with, even if I refresh the feed. Is it because this platform has not enough users?
Lemmy ux isn't focused on keeping you engaged all day. There are no ads to sell, no data to mine.
It's a smaller platform. So there's less on here if you're used to Reddit/etc. Which algorithm are you using? Regardless, all the algorithms are simpler - nothing is going to track if you've seen/interacted with a post already. That's some TikTok/YouTube thing.
My unsolicited advice is find some communities you care about, check in once or twice a day, and share a post of your own from time to time. Lemmy doesn't do dopamine hits the same way corporation owned social media does.
Edit: also, welcome to Lemmy! It takes a minute to adjust, but I've been here for 4 years and I dig the vibes.
