This isn't about theory per se, but I'm trying to find a few new sites to browse through when I'm bored. UG has great articles and lessons, but as much as I love guitar, I'm equally passionate about the bigger picture. The more info I can absorb, the better.

That said, I'm looking for sites that have articles and lessons and resources, etc. dealing with a broad range of topics -- including but not limited to theory. Sites I can open, browse for a few hours, and walk off with some fun new knowledge to toy with. Or things I can experiment with as I read. I'm not exactly sure.

UG is, so far, the only bookmark I have like that. There's this, and I think that's what I'll browse for now, but the more the merrier.
