I had better be more careful. Do I really want to let down on my "image?" I teach high school boys, who don't read English, unless they're forced to. The chances of their looking at my blogs are rather slim. But I have to be careful about my bosses and the students' parents or anyone who can put two and two together.
It isn't quite the same situation as described in a New York Times article, which concentrates on how some professors are using facebook to appear more human to their students.
