What I like about it is the ability to bubble up domains that are more useful to me and also downrank or filter out the ever growing domains of seo filler.
The ability to rank domains up and down is the main reason I feel kagi is worth the price. A few coding sites are raised. Quora, pinterest, and a few other noise sites are blocked. It's like Google from the early 2000s when you could find what you were looking for on the first page.
