If you don't like Facebook's privacy rules, just want a few minutes, they'll change.May-28, 2010
There has been so much in the news lately about FB privacy. It has become increasingly complex and more granular. Furthermore FB assumes you want less privacy and automatically include you in their new data sharing schemes. To maintain your privacy, you have to actively manage this and you must constantly turn off the new "features".
Finally, FB is rolling out a new, simpler interface that should help quite a bit.
There are lots of articles about how to change your settings. I found this one to be one of the better articles on this topic because in addition to the how to, it also provide advice and recommendations.
The FB changes are still rolling out so you may have to wait just a bit to see the on your page.
