Teens still too trusting?

I wonder if much has changed in five years? Have we grown more lax in our diligence about protecting our identities? Or is distrust just commonplace now?

The following paragraph is from a 2005 paper, Gender, Identity, and Language Use in Teenage Blogs, published by the Journal of Computer-Mediated Communication, written by David Huffaker and Sandra Calvert (for Georgetown University). This study examined language use and online identity in teenaged bloggers (male and female), revealing that this group is far more trusting - sharing real names and locations, for example, very often sharing personal information in the virtual world that they would not consider sharing elsewhere:

"It is intriguing that blog authors often reveal their real names, along with other personal information such as age or location. In a virtual world, where identity is flexible, why would authors choose to present themselves as they do in nonvirtual worlds? Perhaps the idea of the personal journal encourages authors to reveal exactly who they are. Perhaps there is a certain sense of empowerment in revealing thoughts and feelings without hiding behind a public mask. On the other hand, if the content of a blog is personal, candid, or intimate, would not a certain sense of anonymity make authors feel more comfortable in being explicit? In either case, it would seem that names, age, and other forms of personal information play an important role in creating and maintaining blogs since these kinds of descriptors reflect the self, and hence how blog authors want to present themselves to others."
