JO interns and blogging

Liz Allen has set some guidelines or ideas for her new summer interns and thier blogs. I think all the princples she mentioned are very important but the most important and one I think all bloggers should follow is if you can't say it out loud or to the person your referring to you should not blog about it. It is obvious that interns shouldn't write about anything that may hurt the company or put them in a bad light. What do you think? What do you think the guidelines should be a summer intern in a newsroom?
