Movies  
Ain't it Cool News: Film geeks apply here.  The guy who runs it, Harry J. Knowles, tips the scale at 350 lbs. and counting.  That's how you know that, when it comes to geekdom, he's the capa da capo.  Lots of advance movie reviews, scoops, and info on forthcoming projects.  
  
The Movie Cliches Page: Lists every film cliche in the book, organized by genre.  Hilarious fun for the Blockbuster generation.  

Roger Ebert on Movies: Even if you disagree with him, his essay-like reviews are never less than fascinating.  The Pauline Kael of the glasses-and-suspenders set.  
  

Comics  
www.warrenellis.com: Meet Warren Ellis, acclaimed writer of Transmetropolitan, Planetary, and The Authority.  He hates you, but that's okay, because he's British and they can't stand real sunlight.  He won't hurt you if you don't look at him.  

Comic Creator Resources Page: Reams of priceless information for aspiring writers, artists, inkers, letterers, and colorists.  It's come in handy for me on numerous occasions already.  

Lea Hernandez: Writer and artist of Cathedral Child and Clockwork Angels, and one of the best women working in comics today.  

Dwayne McDuffie: The brains behind the late, lamented Milestone Comics.  A hell of a writer, as you'll see if you peruse his site.  Some neat comic scripts for those of you who'd like to pursue that as a vocation.  

Comic Book Resources: An online weekly comics mag, featuring the hilarious hatred of Warren Ellis' column "Come in Alone", as well as the good-naturedly vicious satire of Gail's "You'll All Be Sorry!"  

Sequential Tart: Another online comics magazine, but this one's monthly and it's done by women, for women.  Women reading comics...I could sure use me one of those.  

Beek's Books: Todd VerBeek is a longtime comics reviewer with a great handle on the subject.  Recommended reading.  His site also features the handy comic book database program CDATA2K.  
   
Herge et Tintin: Le Cyber-Catalogue Complet: A huge reference to all the Tintin sites on the web.  If you haven't read Tintin, you need to.  
  

Politics  
The Mirrorshades Postmodern Archive: The Web home of acclaimed SF author Bruce Sterling.  The unofficial conscience of the science fiction genre, Sterling is one of this decade's great thinkers, media critics, and raconteurs.  Interested parties should download his excellent non-fiction book about the history of computer crime, The Hacker Crackdown.  You can download this book for free, and I highly recommend it.    

Slashdot.org: A techie spin on current events, politics, science, and entertainment; regular readers of Wired should feel right at home here.  Most useful for getting a feel for the way Silicon Valley types view things.  

Bare-Faced Messiah: Here’s where you can find the complete text of the withering biography of Church of Scientology and "Dianetics" founder L. Ron Hubbard, Bare-Faced Messiah. The page also includes links to articles detailing the Church’s desperate efforts to suppress publication of this important expose.  
   

Humor  
The Onion: Wicked, wicked political humor at its zenith.  How can you resist headlines like "Jesus Christ Kills 2, Injures 7 in Abortion Clinic Attack", "Congress Approves $540 Million for Evil", or "AOL Acquires Time-Warner In Largest-Ever Expenditure Of Pretend Internet Money"?  

The True Religion: Founded by a bunch of yabbos from South Carolina, (including my onetime correspondent, the late Cronan Thompson) the True Religion and its political wing, the World Oligarchy, have laid out their detailed plans for ruling the world.  Dozens of members and growing...apply now and you may still be saved.  
   

Software  
Napster: A wonderful program that lets you find every MP3 you've ever dreamed of having.  How can I find it in me to fault a program that yielded not one, not two, but three remixes of the Doctor Who theme?  A must.  

Get Right: Ever spent hours chasing your family away from the phone in a desperate attempt to download that 30MB demo?  Herein lies the answer; the program lets you download stuff incrementally, as well as scheduling dial-in and hang-up times.  I've used it a bunch.  Recommended.  

Winamp: For actually playing all those MP3s you get from Napster, you criminal bastard.  

CDATA 2000: Shareware program for keeping track of all those mind-warping comic books, for the obsessive-compulsive among you.  
   

Miscellaneous  
The Lurker's Guide to Babylon 5: If you're watching Babylon 5, it would behoove you to browse this site religiously; it contains all sorts of annotations and commentary from J. Michael Straczinski that help the show make considerably more sense to non-grognards.  
   
A. Friendly's Books: My beneficient employers.  Here you can browse their catalog and order books directly with a credit card.
