I couldn't resist a shameless plug for my search engine that I recently launched: http://www.moreofit.com
I often find myself in need of an answer to the question: what are the most popular sites that have to do with x, y, and z? If you're looking for high quality websites about something, just type in a few keywords and have a go. Sorting by popularity (# times bookmarked on delicious) has turned out to incredibly useful, as it's highly correlated with quality. Also, I suggest that if you find any website that you like a lot you query it and see what comes up. Often times there'll be something even better... Or worse. (Did you know there are like 10 urbandictionary clones that all suck yet somehow manage to sustain themselves?)
To answer your original question:
wikipedia, urban dictionary, metafilter, news, pg essays, past and present Harper's indexes, tech/startup/entrepreneur blogs, TED and fora, and once inawhile popurls.
