I used to be able to find personal and small blogs on google. Blogosphere died when google changed algorithms and it ceased to be possible. They stopped coming out in searches even when I was able to quote the title and parts of the content.

Blame google enshittification for this one.

Yes I like kagi's "small web" search source a lot for this reason.

However 99% of people don't use it (probably higher than that) so it doesn't really help with discoverability.
