How Sticky is Facebook?

The article from the New York Times was very interesting. In my opinion, the issue of security and confidentiality is being adressed in this piece. As an educational piece it certainly did its job, I had no prior knowledge of this policy on Facebook. The inability to rid yourself from the database is sort of a mixed blessing however. While the article focuses on the inconvenince and intrusion of privacy, Facebook's intentions may prove useful.
For example, the list of members may be used to research various issues by sending out surveys, or questionares. Also this database may serve as a kind of internet census of on line users based on their interests through the method of click through advertising for example.
However the meat and potatoes of this article is clearly the issue of security and intrusion on the privacy of the end user who registers on Facebook. Many great examples within the article convinced me that I would be totally against the policy which the website abides by. Furthermore I would not want to register as a member until Facebook decides to change its policy, after all I do not want to have to complete the 2000+ steps to delete my account for good if I ever had to.
