I've been playing this game since Classic and I have a lot of fond memories in addition to a few negative ones. It's funny reading the "Vanilla was so awesome" threads because it will always spur the rose tinted lens vs. golden age arguments.
I was sent this blog by a friend of mine and truly enjoyed reading it. It reads like an autobiography and is perhaps one of the most unbiased recollections of what it was like playing in Vanilla/TBC/WoTLK. If you want to relive the "old days" or just want an insight of what it was like playing WoW in it's infancy, this is a great read. You get a sense of the epicness that PvE was back then AND all the headaches that we faced.
Enjoy!
