Data on search engine market share is available, but I wonder what that looks like for Lemmy users in particular, who I would assume lean more technical than the average user, so probably use DuckDuckGo and alternates more than Google.
I use a mix of DuckDuckGo and Kagi. I'll also use ChatGPT, which can be good if you're careful to verify the answers it gives you as a check against hallucinations. It's useful for short, direct answers without ads or SEO bullshit.
Currently down for updates, but does a great job of avoiding SEO abuse/blog spam/etc. Takes you back to the earlier days of the internet when it felt like there were more forums/individual sites/etc. They’re still out there, just hidden under all the junk.
