In this article "I don't bleepin' believe it" ComputerWorld reports on a UK insurer raising rates on social network users. The reason points back to something I have been talking about for some time. People post travel information to their social network sites. They say when they will be away from home, and for how long. This is perfect fodder for thieves, who can typically also collect enough information about the posters to identify them and find where they live. This is why I don't blog, Twitter, or otherwise post about conferences I am going to, even though it would be great to use social networks to connect with folks at the conference or in the conference city.
