Links

Photography:

www.fredmiranda.com - Pretty much one of the best resources I've found for information on camera equipment, including reviews and discussions.  Before buying SLR equipment, check this site first.
www.bhphotovideo.com - The benchmark for pricing in the photography industry.  For most equipment, I've never been able to find the same thing for as good a price anywhere else.
www.beachcamera.com - A relatively local store that I've been to a few times that can come close to or beat B&H's price sometimes. 
www.keh.com - A place to look for used camera bodies and lenses if you don't trust ebay.

Dating/Profiles:

www.flyguycrew.com - One of the sites I work for, FGC has a lot of hot people, with new stuff being added to the site constantly.  There are photos (some by me), rating, forums, and a lot of other good features.
www.myspace.com - For the 3 people left on earth without a myspace...here's the link.
www.okcupid.com - I discovered this testing site a while ago and signed up, eventually realizing there were also profiles on there.  Tests are fun (make your own too), and the matching system tends to work well.

Computers:

http://accelenation.com - I used to write for Accelenation - a smaller site compared to some of the ones in the list here, but a group of people dedicated to bringing you news on the latest hardware. 
www.sharkyextreme.com - How I miss the days of Alex, Ben, Joan, and the entire oldschool crew.  Still, a great place to find out about computer stuff.  Thanks for the front page links a few times guys.
www.hardocp.com - Probably one of the most popular sites for people into high performance computing - Kyle and the rest of the guys are great.  Few of my articles were linked to on [H] and I really appreciate that!
www.anandtech.com - Yet another of the big 4 review sites - this site is aimed at a more corporate kind of PC user who needs to be kept in the know.  Thank you for the link as well.
www.tomshardware.com - Ahh yes, Tom's - an all-around good source of info, plus some fun guys to work with.  Had fun at the GXL, thanks for posting a pic or two of me heh.
www.grid.org - Help find a cure for cancer - donate your spare CPU cycles.  Download the UD agent, set it up once, and let it help the world by finding what interacts with certain cancer proteins. 
www.yoink3d.com - The site that got me started writing...and at it's high point - one of the funniest sites I've ever really been to.  The review of the Kyro card years ago was priceless.  Now, I believe it's all video...

Funny Stuff:

www.userfriendly.org - Online comic strip for nerds...especially the *nix variety.
www.digicrime.com - Order the desktop counterfeiting software here - but be warned that they don't accept cash.  Really, it's a site that exposes vulnerabilities, in a really funny way.
www.lazlow.com - Sunday nights on 92.3 in the NYC area, Lazlow, Big Wayne, Reed, and a collection of guests talk about drugs, theft, 'the internets', and various other important topics.  Funniest thing on free radio. Period.

Cars:

http://forums.mazdaworld.org/ - If you own a Mazda Millenia, and don't know of MW, then you're missing out.  A forum unlike any other, it is funny as hell as well as informative.  My job there?  Try to keep the peace.  That, and unofficial photographer.

Games:

www.gopostal.com - I love Postal² - but it's certainly not a game for everyone.  I can be seen sporting my Running With Scissors shirts very often, and my 3 RWS road signs are all prominently displayed.  Thanks Mike and Vince.
