Astronomy
SpaceWeather.com	Among other things, check out any and all solar activity for the day.
Heavens-Above.com	A kick-ass site to get astronomy info for your area. Complete with star charts showing the positions of the planets at any given time, the current position of the ISS, comet information, and more!!!
SkyViewCafe.com	Another awsome skychart site! Not only can you find when and where the planets will be located, but so much more in provided! Want to know which of the Galilean moons you're seeing when looking at Jupiter thru a telescope? Well, this site tells you, along with so much more!!!
NASA's Satellite Tracking	Wanna see the ISS? How about the space shuttle while it's in orbit? Well, this site will help you spot them (assuming light pollution isn't a major problem in your area).
Astronomy Pic of the Day	Thanks to a certain Miss Rebecca, this site is now among my daily routine for a fascinating astronomy picture each and every single day!!!
A Layman's Brief Guide to Astronomy Terms	What'd he say? An equi-what? Astronomy jargon got you confused? This site might help you out (key word being "might" :P)
Games
Yahoo! Games	Plenty of games, brought to you by Yahoo! DUH! :P
JigZone.com	A site with tons of online jigsaw puzzles!!!
games.apropo.ro	A site with a few simple - but fun - games. Smack the Penguin is a great game :)
CorporateDump	A great site to visit if you want to waste time while at work (or from home hehe).
Software
Mozilla	By far one of the best Web browsers out there (definitely pawns crappy IE)! Complete with built-in (but smart) pop-up blocking and tabbed browsing (the best thing to hit Web surfing since... well... the invention of the Internet hehe)!!!
Trillian	Got an AIM, MSN, Yahoo!, and ICQ account and use IRC? Trillian is an awesome all-in-one program that combines all five chat programs (although Yahoo! doesn't quite work as good as one would hope).
Crimson Editor	This is what I use now for creating webpages. Excellent program (although the spell-check leaves for something to be desired).
AVG Anti-Virus	An awesome (and very free) anti-virus program! No subscriptions needed, unlike certain other suites *coughNortoncough*
Ad-Aware	I hate spyware! It eats up system resources, bogging everything down in the process, and it opens you up to numerous malicious/annoying things that are out on the Internet today. Ad-Aware is a great little program for detecting and removing those programs that have been installed on your computer (without your even knowing it!) which pose a threat. Like a good anti-virus program, a must have!
Misc.
MySpace	A social networking site that allows you to meet so many people! And as a testament to how good it is, before I joined in August of '05, my friends page had just two people on it! And with how difficult it is for me to make friends, the expansion noted is quite significant!
ImageShack.us	Cool image hosting service I'm using for the images on this site. 100% free with no bandwidth limitations!
The Bounty Hunters Guild	A role-playing group that I'm a member of based on the bounty hunters of the Star Wars universe. The character that I use can be found here.
Weather.com	From the trusted people at the Weather Channel, get detailed weather for your area, or anyplace in the country.
The Phobia List	It's truly amazing that there are so many phobias out there. Amaxo- and Hydrophobia are two I'm all too familiar with (although Amaxophobia is also the fear of driving). There used to be a kick-ass shirt they sold, but I can't find it, but if someone wants to buy me that poster hehe, I'll definitely take it. :)
HumanForSale.com	How much are you worth on the open human market? A fun little site to find out just that. Anyone with a spare $1,998,370 is free to buy me hehe!
Wikipedia	A kick-ass online encyclopedia.
Webopedia	A nifty site to go to look up what the various acronyms and other terminology used by geeks the world around.
The Urban Dictionary	Ever been chatting with someone, or reading a website, when you come across a piece of slang that you don't know what it means? This is a great place to go to help bring you up to speed on the latest slang.
Persian Kitty - Weekly Pose & Background	Weekly pics and desktop backgrounds of some very hot (and very naked) women. ;) What can I say? I'm a guy hehe.
