I figured I would explain to new readers why I chose the links that are on the main page.  I'll also post this in the about page for future reference.  I'm not going to place links to them because I'm lazy, and the links are in the sidebar to the right. ^_^

• BBC Documentaries - First, I have to admit that I don't frequent BBC.com that often, but rather, I subscribe to the podcast.  They provide 20-30 minute long audio podcasts on a variety of subjects, and provide an international perspective (unless you're UK).
• HowStuffWorks - Another website that I don't actually visit often.  They do have two audio podcasts, though, which are right up my alley; "Stuff You Missed in History Class" and "Stuff You Should Know."  The subject of the former is pretty obvious, while the subject of the latter tends to be somewhat random, yet still profoundly interesting.  The quality of both podcasts is very professional, but I wouldn't expect anything less since the site is owned by the Discovery Channel.
• Mental Floss - This is easily one of my favorite sites, and a site that I actually visit.  Mental Floss is full of awesome bits of randomness and have a great quiz/trivia section, too.
• My History can Beat up Your Politics - This is another audio podcast, but this one examines current events through the prism of history.  I started listening last summer, and was completely sold when, using historical analysis, he predicted in the spring, an Obama victory in November.
• Snopes - Sometimes your mom sends you a crap forward that you know can't be real (otherwise humanity is screwed).  So you go to Snopes, and they sort it out for you.
• TED - This is an excellent science and technology related site.  And I'm talking good, earth-shattering, paradigm-shifting science, not the science of increasing your virility and growing more hair.
• CIA World Factbook - Opinions of the CIA may vary, but one thing is undeniable; they know their stuff.  Now if they just knew what to do with it.
• Wikipedia - In my honest opinion, this is the best site on the web.  Free, open-source, collaborative information.  Sites like Wikipedia cause Stalin to roll over in his grave.

Of course, none of these are actual blogs, they're more links of interest, but now you're just arguing semantics.
