Web searches now are terrible. It doesn't really matter which search engine you use, for a lot of search types, the results are just bad. This isn't entirely surprising - history has rewarded user-hostile behaviour, and the interests of search providers are typically not aligned with their users (HN discussion, pagerank is over).
The best and most interesting sites I find to read I typically find via a link from another site I like (webrings anyone?) or via a comment somewhere like Hacker News (which I suspect often come from a site that another user frequents, so pretty much the same thing).
To that end, here in no particular order, is a non-exhaustive list of other sites/blogs/other web stuff that I get some enjoyment from.
Rat Factor Lots of interesting posts on a variety of topics (typically techy) and some cool artwork to boot!
Low Tech Magazine Probably one of my favourite sites - I love old or obsolete tech. I really enjoy the detail into which he goes on seemingly mundane topics.
Alex Harsányi's blog Great source of well-written posts, primarily about Racket's GUI toolkit.
Solène's blog Primarily quite short OpenBSD workstation related tinkering. Real-world day-to-day problem solving, which I always find interesting, though I'm not an everyday BSD user.
The Tildeverse. A network of pubnixes aiming to bring back the community of the internet of old. A couple of examples: cosmic.voyage (collab. sci fi), tilde.institute (OpenBSD). Related: SDF.
