I know this is bot post, but for those interested here's a link to the Kagi blog explaining what this is, https://blog.kagi.com/small-web
TLDR; Kagi is basically promoting recent content from small blog posts and websites that difficult or impossible to find with google or the other advertising based search engines. This helps you finding interesting content that is not based on click count or corporate advertising.
My Mini has also been fantastic! I've been running it for about a year with almost no issues, primarily printing petg. Far more reliable than my last two Enders which surprised me. I also just recently upgraded my extruder, heat break and nozzle with Bondtech equipment, which has produced some great results.
