Should teachers be punished for personal posts on social-networking sites?

As the popularity of social-networking Web sites such as MySpace and Facebook continues to grow, so has the risk for teachers who post personal pages on these sites. Teachers have been suspended and even fired when the wrong person -- in some cases, a student -- stumbled on their page.

Though some people feel that pages that reference social drinking and other adult pastimes set a bad example for students, others believe that teachers' online posts are no one's business but their own. Can pictures and writing displayed on a personal Web page qualify as "conduct unbecoming"? Or do teachers have the right to express themselves as they please outside of school grounds?
