I voted no.
I can keep in touch with people through my personal e-mail that the whole world can’t read.
Everything about your life does not need to be online… isn’t anything private anymore?
My kids have already been informed that they are not allowed on these sites. (myspace, facebook, etc.) If I caught them putting up accounts in defiance of my directive, I would get rid of my computer and go back to paying bills with checks and snail mail if that’s what it would take. There is too much risk, not only from predators, but from undeveloped childhood/teenage judgement. If you do something stupid IRL, it may not necessarily haunt you all your life. If you do something stupid online, it will exist FOREVER in its unaltered (as in, untempered by time) state. Even if you delete it 5 minutes later, someone could have copied it and saved it to a file. And speaking of predators, I don’t care about their “new” safety features. Too little too late. Where were they for YEARS as people complained about children being endangered on their sites? They didn’t care enough to do anything about it until they were getting hit in the wallet by lawsuits.
