Does a teacher have any business being on Facebook?

This is pretty interesting considering all of us who have Facebook accounts.  It comes from a Computers and Composition article written by Gina Maranto and Matt Barton.  They report:

“In October 2007, the Ohio Education Association sent out a memo advising its 131,000 union members to avoid joining social networking sites such as MySpace and Facebook and urging teachers to “complete the steps involved in removing their profile” (as cited in Wildeboer, 2008, para. 1). While acknowledging that “this advice might seem extreme,” the memo claimed that “the dangers of participating in these two sites outweigh the benefits”

I’m looking forward to taking a closer look at the above article and some others like it.  What do you all think?
