I've written a post on how some small and unexpected things in WoW can delight you and be something you will remember forever. not the big questlines and NPCs blizzard makes sure nobody will miss or every guide makes sure to mention, but the more hidden places or special characters in the game that still offer something unique or entertaining to those that can find them. I would absolutely love to read about more such secret places or NPCs in wow, I have a feeling that there's quite a few I've missed!

this could be a very interesting topic more bloggers might enjoy(?)
For reference, my latest topic:
http://raging-monkeys.blogspot.com/2010 ... arans.htmli wouldn't want to restrict the topic to NPCs only, but ask generally: what wow secrets have you discovered on your long journey through the world of warcraft? what unexpected, surprising or delightfully 'pointless' things have you chanced upon that add something special to the game for you?
