When I started teaching, I would get miffed if a student asked me to write him or her a recommendation for law school - I'd feel like that's not what we were doing in the course. But now I see that person as someone who might be gainfully employed. I bring in a lot of people to speak to my classes, and I've gotten to the point where I've expanded the type of guests I invite to include people both inside and outside of the traditional publishing world.
