I’ve gone and changed all the settings I can find to what I feel comfortable with but the problem for me is that I keep finding more and more settings that need monitoring. Navigating through the morass needed to edit a person’s settings is the main issue for me.
Another thing is not all of us are logging in daily and thus have no idea that changes have been made by Facebook. It would be easy enough for them to notify everyone via email of these changes when they happen. My web host service notifies me when an installed app on my site should be updated. Even my ISP emails me on changes to services such as webmail.
Facebook seems eager *not* to let people know of changes and how to make edits.
