I have discovered the evolutionary purpose for trade chat.
By housing the ingrates that populate trade chat, Blizzard has managed to keep enough of them occupied for long enough to allow a miracle to happen.

I think Blizzard should be commended for their work in cleaning up the gamer gene pool for so long.
On a more serious note, Isn't it amazing what can happen when a bunch of gamers get together to solve a problem?
