Blogging Restricted for Teachers?

I read with interest an article published in The Sunday Times about teachers blogging... It is quite sad if teachers are being monitored on the net for what they had blogged. But to a certain extend, what the article had mentioned is quite true too...
Being a teacher is like a mini-celebrity (Except that we do not command a 5-digit salary and endorsement), in the sense that for every little mistake u make, the next day headline is about you and you only...
If you have alreadi identify yourself as a teacher in the blog, then I guess there is a certain kind of restraining order that you have to make for yourself..Just follow the below mentioned and you are safe...

Certain donts:-
(1) Posting of your sex life (Photos included even if it is so sex-citing)
(2) Bad-mouthing of your skool or even your students
(3) Unflatering photos of yourself in case it is being circulated around in class

Anything more to add in to this list?
I dont have an interesting life, so I know for sure I wont be monitored lah... Hahaha...
