I've had this running through my head this afternoon.... "Why do we always come here / I guess we'll never know / It's like a kind of torture / to have to watch his glow" (now watch me actually win a battle cry roll tomorrow and have to come up with something new!)
I just felt that eventually, we'll have a lot of people working on the achievement and they might want to share their selfies. So Wor says, "Hey look at the selfie I took in Dalaran last night. There was a warlock who photobombed it."
If we have just a folder with no threads, either you start a thread every time you take a selfie and things get huge or you add to a "Post your selfies here" thread and it become, like the "Did you really just say that" thread, 44 pages long.
