Wow, I agree. Lately I've noticed search sometimes just pops in websites just because I visited it from a previous search, relevancy be damned! and it suuuuuucks.
I seem to be able to find a much more limited selection of content than I used to in the past. It used to be that even obscure search queries turned up something useful, but now you either get nothing or the same old big or commercial sites. There has to be tons of content out there that Google just can't seem to find anymore.
