2) (submitted by colleagues) I thought you liked Penn State?

There were very few places for which I would have left Penn State. A couple of them came calling.
At the same time, I have to admit that I don't feel a lot of loyalty to my employer. I look at what universities do to the junior faculty, and my sense is that it is every man/woman for him-/herself. (If it were up to me, I would fire the senior faculty when a person doesn't make tenure because generally (1) they hired the wrong person in the first place and (2) they didn't provide support/guidance.)
