This is really creepy. I knew that there would be adds out there as soon as the achievement system came about, but as I read this, was dumbfounded. A few months ago (well after your original post) I had a conversation with my wife about writing an add for her new favorite thing in WoW.
I told her I would name it Overachiever and that it would be an evolution-project that started of with things like the critter, drink, and book tooltips; but would work up to the BG related subzone checks and such. I am astounded that those same exact things that I pitched to her had already been written exactly as I had described. Wow, I'm just amazed.
