There are no recommendation algorithms like in YouTube or TikTok here, if posts that are alike and get sonewhat the same amount of high votes, you most likely will see them one after the other. There isn’t a way around it really.
Anyways, it’s better if you subscribe to communities and mainly uss the subscribed feed along with a good algorithm like Scaled (gives a boost to posts in communities that aren’t as active as the others) or maybe just Active.
I rarely use the All feed, only when I try to find new communities honestly.
I do like SearXNG over Kagi due to their prcing and AI bs but Kagi really just has better search results.
