I don't think that's ever going to happen. Social networks, contrary to smoking, are built on the very nature of human beings: being social animals. And that's certainly not going away. It would be like wishing that the buddies socializing on the corner would be looked at the same as the guy smoking next to them.
There's no doubt that our natural inclination to socialize is being used and twisted through these slot-machine social networks, but if you're going to wish for something, wish for better social networks, or better education to help people control themselves, just not for humans to stop being social.
