CNN iReporter Tom Martin says that, although Facebook is free, users pay the price of having their information become more and more public.
"I do not want to be a part of this apparent mission to alter the norms of society," the 23-year-old said. "Facebook has frequently changed its privacy settings in the past and will do so again, always in favor of less privacy."
Martin admits that he misses the occasional party or event by not being a member of the site - "there is somewhat of a social price to be paid for rebelling against the trend" - but also says he wouldn't sign up for Facebook "if you put a gun to my head." He believes people who really care about him will make the extra effort to stay in touch.

News of a study that found coffee may lengthen your life was tempered by the revelation that there are a whole bunch of asteroids out there that could pose a threat to Earth. What is a CNN commenter to do?
I am sitting at my desk having a cup of java, keeping my eye peeled for stray asteroids. I am deeply torn. The coffee may lengthen my life only to face an untimely demise by an errant rocky missile brought forth from the heavens. Ignorance is truly bliss.
An asteroid would strike so fast you wouldn't even comprehend what was going on until after the fact. It's not like in the movies where the asteroid takes its time, slowly drifting through the atmosphere - those things move, like a bat-out-of-hell. So enjoy your drink; if you die, you won't even know it.
