It intimidates me a little that Stephen Colbert followed me at twitter. (Even though he's one of those guys who follows thousands of people.) I don't know how he found me. When I tweet, I wonder, "is it worthy?" I sometimes check my friends list to see if he saw his mistake and has unfollowed me yet.
I followed him in reply. But he tweets too much, and I might unfollow him. A little part of me thinks, "What right do you have to unfollow the mightly Colbert?"
