Any time I'm having trouble getting actual work done, I like to barge in on other people and make it harder for them to work too. That's why I was over at Rerouted River National Laboratory the other day, hanging out in the office of somebody who insists that I refer to him as "Dr. N." This used to be his way of keeping me from jeopardizing his job by writing about what he actually says, but now he's also a big-time blogger, with scads of Twitter groupies who know him only as "Dr. N." So now, if I were to point out that his real name is Barlow Culbertson and he never got a doctorate, it probably wouldn't create a ripple in the blogosphere; he's much too cool as "Dr. N" for his first-life persona to matter to anyone.
