I find this poll very dubious to say the least. I’m guessing there’s a serious methodology issue in the surveyed population. A very tech savvy crowd would have a much higher awareness of Facebook privacy issues, and would also be much more likely to have a strong, and or negative, opinion of the privacy issue than the average casual social networker.
From the link:
More than half of Facebook users are considering dumping the popular social networking site because of privacy concerns, according to the results a new Sophos poll .
Abingdon, U.K.-based Sophos said 16% of poll respondents said have already stopped using Facebook because of privacy issues. The results of the online poll of some 1,600 Facebook users, released this week, found that 30% are “highly likely” to quit Facebook due to privacy concerns, and another 30% said it was “possible” they would leave the site for the same reason.
Meanwhile, 12% of respondents said that won’t leave he site and 12% said it’s “not likely” that they’ll quit Facebook
