The other sites which kick the second most ass.
Ain't it cool news
Excellent launch pad for keeping up with the latest movie news. Also the standing example of how the internet has reached into and affected the "real world." Along these lines, I'm also a fan of CHUD
Netflix has been the best way to rent movies for years, but more recently their streaming service has been excellent. Thousands of movies, full seasons of TV shows. Really good stuff.
The Internet Movie Database. Enough movie information to choke a deep-throated porn star. And if you're in need of an IMDB for music, allmusic will be right up your alley.
This is a free, wiki-style encyclopedia (meaning anyone can edit it). It contains information that simply can't be found in other encyclopedia, like Star Wars Kid and Tecmo Super Bowl.
Digg is my favorite of the community link aggregators. You can always find something interesting here, from the latest viral videos to current news to funny photographs.
This online magazine is simply the shit. They post updates and new articles throughout the day on topics which are always relevant, interesting, and well-written.
The best website covering video games, gaming and industry news. GameSpy and GameSpot are also excellent video game sites: reviews, previews, news, and more. And GameFAQs is where I go when I get stuck in a game.
When it comes to search engines, Google is still the best. 1/13/06 Update: True dat. Double True!
The two most important newspapers on the web are the local rags which cover the New Orleans Saints and the Sacramento Kings. For generic sports news and info, ESPN and Sportsline are excellent. For official league news and info, the NFL and NBA each have their own site.
