http://library.uncg.edu/news/ - Newspapers Online. Any medium to large newspaper in the world can be accessed easily from here. I catch myself referring to this page quite frequently. (It's one thing to get a blurb on, say, the Tour De France from USA Today, it's quite another to read about it in a Paris paper.)
http://www.heavens-above.com/ - Heavens Above. Much info about all manmade satellites, and most nautral ones too. Find schedules for viewing Hubble, ISS, or Shuttle passes (if we ever launch another) radio satellites or almost any other satellite, along with a wealth of info about comets, planets, etc.
http://www.imdb.com/ - Internet Movie Database. No movie question goes unanswered. Every movie (or TV show, or video) you've ever heard of--and every person who ever worked on it--is buried somwhere in this database.
http://www.aldaily.com/ - Arts & Letters Daily. A clearinghouse for serious magazine articles, essays, opinion, book reviews. Politics, science, left-leaning, right-leaning, friggin' name it. (NOTE: The left margin of this site is beyond belief: seemingly every newspaper, columnist, blog, radio...it's unreal.)
http://www.howstuffworks.com/ - How Stuff Works. When someone asks you why the sky is blue, don't shovel them a load of shinola by saying "it reflects the blue water of the ocean." Go here, learn, and explain.
http://www.yforum.com - The National Forum On People's Differences. If you've ever had a earnest question about a different [race, gender, sexual orientation, nationality, religion, age, socio-economic class, geographic area, occupation, etc.] but were afraid of how you'd be perceived for asking, YForum is for you. It works like this: you ask an earnest question, and someone from the group in question reads it and gives an earnest answer. So simple, yet no one's come up with it until now. A brilliant avenue for real learning and understanding.
http://www.google.com/language_tools?hl=en - Google Translator. Frustrated by writers who show off with French phrases, like "comme il faut," or "Tour de France?" This site can translate virtually any phrase from English to French, German, Italian, Spanish, or Portuguese, and vice versa. http://babelfish.altavista.digital.com/cgi-bin/translate? - AltaVista Translator. This site translates English to Chinese (or so it claims to.) Also adds Dutch, Greek, Japanese, Korean, anbd Russian to Google's language list. NOTE: Alta Vista is listed 2nd here becasue many of it's modules don't seem to work. (Chinese, Japanese, Greek, etc.)
http://www.timeanddate.com/ - Time & Date.com. If you're REALLY a time junkie like me you might like this page. Set up your own world clock with the time in any time zone on Earth, and much discussion about different kinds of calendars, leap years, etc.
http://www.tevasandals.com/ - Teva Sandals. In 1996 I took my Tevas and a pair of sneakers to Atlanta for our 5-day stint at the Olympics. The sneakers never left the suitcase. A visually interesting page too.
http://www.quisp.com - Quisp. I worshipped this cereal as a kid. Quisp & Quake? Remember? Long Island to Lompoc? Anyway, I love it, but then one day, pfffft...it was gone! You can still find it, but only in a five or six cities, but you can buy it online.
http://www.keyflux.com/titanic/ - Jim's Titanic Site. A phenomenal amount of detail about the doomed ship, including an interesting FAQ for people who've seen the movie (it answered many questions I had after seeing it).
http://www.google.com - GOOGLE. This is a leftover link from 1999 when no one knew what the hell this was. You can actually get better at Google. You can use it as a dictionary, calculator, metric converter, etc. Go here and use the individual links OR do what I did and DL the PowerPoint file.
