I would imagine many wow players are avid readers of Wow Insider. Wow Insider is a warcraft news blog that writes about anything and everything Warcraft. They pull information from all over the web and other blogs, and they also have featured articles that run daily or weekly. They're usually quick too, so when you're looking for the latest patch notes or class changes or new information on wow books and game changes, it's a good place to start. And they site all their sources so you can see the original information as well.
Just last week Wow Insider became WoW.com. Other than the address change, the major difference is that they now support member profiles where you can add your characters, upload pictures and blog entries and keep track of other people who sign up as well. In addition to all of that, you can download an add on that will let you upload information about your characters in game. For instance, I could run the instance and upload to my profile after a raid showing any avhievements we completed that night. It tracks a lot of different things. And you can make notes in game that will upload to your blog when you run the addon.
It's basically a Twitter/Facebook meets WoW amalgamation. And it's kind of fun. That being the case, I don't have anyone actively following me, so the information is only for myself. I'm curious if anyone else out there is using this and enjoys it? If you'd like to follow my characters, I'm using the name gmazeroth, or you can look up Elionene and the other characters I play.
