Change your profile pic on Facebook?

There's a lot of buzz going around right now about the Facebook user campaign to change profile pics to raise awareness of child abuse.  There's also a lot of talk about it being started by a pedophile as an attempt to entice children to approve their friend requests to them.
First of all, I think it's a wonderful thing that we as individuals can influence and inform so many people through social sites like Facebook.  But I think we would all do better to donate $5 to our favorite cause rather than change our profile picture.  Of course, it wouldn't hurt to do both! There's nothing wrong with having a little fun and being even a bit silly at times.  But how much more good could be done for all these causes if we took even a small amount and donated it to legitimate organizations that work for our favorite causes.
As for the pedophile angle, here's my two cents worth.  Even if this was started by a pedophile, would that really change anything? If you're being a responsible parent, you're monitoring your childrens' activity on Facebook and the computer in general. And while we can't keep an eye on our children every moment of every day, there are things that we can do to protect our children.  A couple of very simple things to do are to keep computer use in a public area of your home and check your computer's history occasionally.  Hold your children accountable by having their passwords for the sites they visit that require them and then occasionally poke around and see what they're up to.
Is that spying? Well, it may border on it, but in these days of technology, parenthood is a whole new world.  It's my personal opinion that we have to be a bit nosy for the good of our children.  After all, if we don't care, someone else will.  And it might just be that pedophile.
