I stopped finding their search competitive around 2015 but kept checking with gradually less frequency, so I can't really comment on whether anything new has added or hurt their results.

Some of their semantic web based info results seemed good and would have benefited by more complex algorithms to figure out when to show it.. But I kind of got the sense that they went into the Amazon territory where no one was authorized to sort anything out any more to get out of some kind of local optimums.

Are you using something better? (Are you a Kagi customer?)

I originally moved to duckduckgo to use their !g/!b/!.. for quick search comparisons when I was very much a power user of search, but these days ddg's first results or results after adding a qualifying word are usually adequate for my usage and my power search skills are in decline.

Interesting I've found it pretty helpful for my searches. Maybe I search for more simple things :-)
