For this question, I'm going to respond with but a single answer.
Seriously, is there anything that search engine can't provide? Sifting through the crap can be tiresome, but that is one location I can always count on to eventually get me to where I want to be. Why would I bother bookmarking anything else?
Alright, fine. Here's a few other sties that I visit regularly, outside the standard wowhead and EJ.
Dark Legacy Comics - they're funny because they're true.
XKCD - I'm a computer nerd who works in an engineering firm, and has Math and English majors for friends. This might as well be my second home.
And that's really it. I have a ton of blogs in my blog reader, but none that I freak out about if I miss a day. Toby gives me all the Warhammer 40k and SW:TOR updates I can handle, and I just don't spend a lot of time on community sites.
Up next - bad habits and flaws. I'm gonna need a longer list....
