Which Facebook Friend are YOU?

To add to the never-ending list of "Which (fill in the blank) are YOU?" -- quizzes that tally your likeness to anyone from Sofia on The Golden Girls to Samantha on SATC -- the SF Chron's Peter Hartlaub offers these stereotypes of the nine basic friends you find on Facebook -- and rates their annoyance factor.

Pretty hilarious. If you're on Facebook, you know them all (though none of them are YOU...)

From his piece:

"What I didn't expect was how much the online social networking community would be just like going back to 11th grade. There are fewer people wearing Depeche Mode T-shirts and more people sharing random things about themselves, and my locker combination has been replaced with a password. But the sting of rejection, the sanctimony of the popular kids, dressing up for picture day and even the random chatter in the hallways is pretty much exactly the same.

"Facebook, which started as a networking site for Harvard University students and is now based in Palo Alto, boasts 175 million active users. As of December, hundreds of thousands of new users were joining each day.

"Amazingly, it's possible to break them down into a handful of stereotypes. Here are nine of the most common friend types on Facebook. Each one has been assigned an annoyance factor, on a scale of 0 to 100. Please add your own categories to the SFGate.com version of this story."
