Tenure is a red herring!

Last weekend, while I was enjoying something on television, my iPad buzzed and kindly informed me that a few people I follow on twitter were all tweeting about #whytenure. Woah! I thought! What's this? Is there something earth-shattering happening with tenure ? I had to find out. I saw some tweets, favorited them (for later digestion), and went back to my show. It seems to me that this was a reaction to Wisconsin and Gov. Walker's most recent attempts to mess with higher education in that state. There is no doubt that feelings around tenure, both in Wisconsin and outside, are pretty charged. I see blind acceptance of tenure as a given by most people I interact with, but I don't see why (despite their arguments). I am one of the few people, that I know in my circles, that holds the unpopular opinion (among people in academia) that tenure is an outdated institution and what's on the drawing board needs to be erased and re-conceptualized from scratch....
