I have a crapload of things on my RSS reader. Not going to discuss the blogs I get through my LJ-feed in any detail, but it's stuff like John Scalzi's "Whatever," Wil Wheaton and Randall "XKCD" Munroe's blogs, and so forth.
(And redtophat: Yeah, definitely agreed with you re: OSC's blog. *shiver* )
Anyway. RSS reader has four categories:
GamingThese are the gaming-related blogs I look at. Most of these are focused on old-school (OD&D/BECMI/1e AD&D), but they have a few generalist posts around.
http://advancedgaming-theory.blogspot.com/http://oldguyrpg.blogspot.com/http://grognardia.blogspot.com/http://jrients.blogspot.com/http://monstersandmanuals.blogspot.com/http://peopletobe.blogspot.com/http://www.rockpapershotgun.com/ (PC games, not RPGs like the other ones here)
http://sandboxofdoom.blogspot.com/http://trollsmyth.blogspot.com/Of these, I strongly recommend Rock, Paper, Shotgun and Trollsmyth. (I like all of them, obviously.)
A Larger World(These are the things I read because I feel I should know more about them)
http://abovethelaw.com/ (Called the "Law Tabloid," it's a very regular and informative blog targeted towards law students)
http://www.infrastructurist.com/ (discusses infrastructure development, primarily within the USA)
http://likearadiotelescope.wordpress.com/ (Science blog maintained by a friend of mine)
Military History/PracticeWhile I'm going to law school next year, my BA (which will be awarded next week, if things go to schedule) is in history - specifically military history. These are blogs which I check regularly, whether dealing with military
history, or, as is more common, military affairs.
http://abumuqawama.blogspot.com/http://armchairgeneralist.typepad.com/my_weblog/http://warhistorian.org/wordpresshttp://globalguerrillas.typepad.com/globalguerrillas/http://smallwarsjournal.com/blog/http://informationdissemination.blogspot.com/ (Naval affairs blog)
Of these, I strongly recommend Abu Muqawama and Global Guerrillas. GG, in particular, has some very interesting takes on asymmetrical warfare in the modern era. (It would probably be a favorite of Parson's.)
News(Note: I also check the built-in BBC feed in Firefox)
http://english.aljazeera.net//default.html (Al Jazeera is
not affiliated with Al Qaeda, as much as Fox News & Co. might like to spread that malicious rumor. They're a valid news source, with some truly excellent reporting. OTOH, take their reports on Israel itself with a grain of salt.)
http://www.dawn.com/ (Pakistan's main English newspaper)
http://kristof.blogs.nytimes.com/ (Nick Kristof's blog at NYT; Kristof is one of the few kickass journalists we have these days)
http://krugman.blogs.nytimes.com/ (Paul Krugman, very accomplished economist)
http://www.salon.com/opinion/greenwald/ ... greenwald/ (Glenn Greenwald's column on Salon; very solid and informed political posts)
I'm going to add fivethirtyeight.com to this shortly, I think. Excellent political analysis.
