Thus far I have found facebook to be a great asset. Like anything it takes a few minutes time to protect yourself which it seems too many simply assume is too difficult to do because they believe the falsehoods spread on the internet or lack the knowledge. We have exchange daughters all over the world and our children are scattered in several states. With facebook we can keep up on happenings, photo's, daily events, surgeries, significant others, etc. In the old days it took days of mail returns to keep up and frankly even sending emails to each and every one of them with todays technology is a burdensome task. So with this new technology of facebook we get to enjoy our family more than ever before and I am grateful.
Be smart and protect yourself and it is a good tool. If you don't use the asset do so because you simply don't want or need to. Don't do it because of baseless fear tactics that get spread out of ignorance.
