Never really had that issue. Are you referring to you sub feed or all? If the issue is all maybe start blocking the duplicates that you deem unworthy of your time.
The lack or rudimentary algorithms lemmy has compared to corporate social media is both good and bad. Less dopamine/doom scrolling but you also have to curate the feed a bit to make it work for you.
Post more my dude. Start the conversations you want to see.
And I’ve never felt better.
I just want the communities I post in to grow. Just trying to do my part to keep people engaged and encourage others to do the same.
