I saw that Scalzi did this and it seemed intriguing so I decided to try it myself. I am going to type each letter of the alphabet into my browser's address bar and see what website it tries to auto-complete to.
A: Arcane Wordsmith, one of my favorite WoW blogs.
B: The Border House, for damn good reason. Because I'm the Lead Editor and Co-founder and it's basically the best website on the internet. ;)
C: Craigslist. I scour Craigslist pretty regularly for Farm/Garden stuff and also for checking out furniture, art, and free stuff.
D: Apple Developer Site. The URL is developer.apple.com, and it's where I go when I'm doing work and need to do some admin stuff for our devs.
E: Ebay. I don't actually shop on Ebay often, but over the last few months I was looking to purchase a saddle and was checking ebay multiple times a day.
F: Facebook. This is a no-brainer.
G: Google, naturally.
H: Huffington Post. I do check the news there quite a bit, especially since it's liberal slanted.
I: iTunes Connect. Another work related administrative site.
J: Jezebel. Happy to see that me and Scalzi have this one in common ;)
K: Kotaku. I read it frequently because I have friends who write there and I think it's made a turn for the better this year.
L: LinkedIn. I check my messages there all the time to see if someone is trying to hire me. They usually are, but not for anything remotely interesting or local.
M: Company Email. It starts with mail.companyname.com, so that's naturally where it resolves.
N: Noxxic. A quick 'cheat sheet' website for WoW strategies. My nerd is showing.
O: Openraid. It's a WoW website where people can connect and raid together, pretty neat concept.
P: Pivotal Tracker. It's our project management software at work and it's highly recommended.
Q: Nothing except wow.joystiq.com.
R: Reddit, duh.
S: Steampowered.com. I shop too much for games on Steam (and don't play many of them, whoops!)
T: Twitter.com. I've been tweeting nonstop since 2007.
U: San Diego Union Tribune. Local news, though they've recently been purchased and they suck now.
V: Virgin America, my airline of choice.
W: Wells Fargo, my bank.
Y: Yelp. I thought it would be YouTube, but I guess not.
Z: Zillow, because we've been house searching.
Kind of a fun little experiment. :)
