Some folks on HN will hate this idea due to the genetic fallacy, but I think we'll end up feeling about social-media the way we currently feel about smoking: it is something that obviously requires protections for minors.
Well, the idea in the link is total bunk (IMHO), but I agree with you. Social Media's turned out to be something with an ugly side, but Pandora's Box is open now and it's here to stay. I would completely agree that we need some protections for minors. Hell - some protections for all of us! I just have no real, viable, solutions come to mind.
