The excellent folks at the Pew Internet and American Life Project have recently released an update of their 2009 report on reputation management and privacy attitudes among US internet users. The ‘top line summary’ says, “Social network users are becoming more active in pruning and managing their accounts” but I would be cautious about suggesting that from the data. True, 63% of them have deleted people from their “friends” lists, up from 56% in 2009 and 44% have deleted comments made by others on their profile, up from 36% in 2009 but since these are measures of “have ever done” one would expect figures to have risen given more than two years have passed.
It’s worth noting that from the report that (consistent with other research) young and old have the same likelihood to set their profiles to be private.
