I use my real name on facebook. That makes me an idiot? Thanks for the classification.

I tend to believe I'm more informed than the average person. Maybe I'm mistaken. If you believe that social networking sites sharing this type of information is the greatest privacy issue at the moment then you are mistaken.

To provide an example, I recently remortgaged my house. I received no less than 2 dozen mail offers to my home address (the address remortgaged). Most of them were to either offer insurance protection in case I was disabled and couldn't pay my mortgage or to allow me, for a fee, to pay my mortgage more often thus saving money in interest. A service my bank offers for free.

These companies put information on the mailings that could only be found in the mortgage documents, including the principal amount. How did they get this information? All of it is readily available public information available on the internet. Any piece of property in the state I live in has this information available online. This includes deed information such as amount paid and any liens including mortgages and tax liens. These are full images of the documents, including the signature. For many cities and towns tax assessment information is also available: property value, floor plans, property acreage and address.

There are many other examples of information online that compromise privacy. To worry about people putting information they themselves decide to put out there is the least of our worries.

Who is the astronaut MTV uses? Have they ever been paid for their image?

"There is nearly a 400 Billion dollar tax preparation industry." Really? Where is this number from? The GAO estimated in 2005 that total compliance cost was $107 billion (using the lowest available estimates). http://www.gao.gov/products/GAO-05-878 That number includes corporations' internal costs for their tax departments.
