To be honest... I am actually tempted to do the "question of the week"...
But I am also thinking of two other people who will fit quite well for the job, Matt Leese and Jessica Boucher.
Maybe it doesn't have to be a one-person job
And of course no one person can think of the good question every week. I think whomever end up doing the question of the week should take in suggestions from the people.
On the other hand... being the question of the week dude will allow me practices in posting short messages.
