It is a little odd but that box is linked to their personal twitter feed and they can do what they want personally. I have no great issue with it, though the more common and specific it gets then perhaps I might change my mind.
Even stranger is that Alexis's tweets keep showing up.
It is a little odd but if the box was bigger, or had a larger page linked to it, I would like it to include certain "Friends of the Site" as well. Though with only 5 spaces that not really feasible.
