Long, long ago, there was a time when I didn't read WoW Insider. When I started playing the game in vanilla WoW, I didn't read anything -- I didn't even know there were WoW sites on the Internet. I got all of my information by word of mouth, and when someone finally told me about Thottbot, it was a game-changer for me. It wasn't until late BC, however, that I even heard about this blog, and I don't think I read it regularly until Wrath.
Keeping track of World of Warcraft news and changes has completely changed how I play the game. Rather than wandering through the world until I come across something interesting, I get a heads-up about new reputation factions, daily quests, mount drops, and craftable items that I can then go searching for. I've learned more about my class, become a better player on my alts, and been assured that it's not just me who hates heroic Grim Batol. I even have an auction addon now, and though I don't play the auctioneer game, I am impressed by those who do.
When did you first start reading WoW Insider? Has the game changed for you as a result? What have you learned about here that you never knew before?
