The first random page it returned to me was this — https://gaultier.github.io/blog/how_to_make_your_own_static_... — which was about building one's own static site generator, which I really liked. I did not realise when I closed that page how hard it would be to find it again, because, of course every new visit to Kagi returns a different page :-)
yeah, same happened to me, the first site I was sent to was a list of people sending in random "sunday thoughts" (or whatever it was called) on (actual physical) postcards which then got scanned and posted. There were some good things in there. Now I can't find that site again because I didn't realize it was randomized...
