Yeah. My experience is that social networks and media are good for distributing information to a group of people who have opted in to the distribution. Which is what I think you are saying. However, social media is often portrayed as substituting for face-to-face social contact, which it does to some degree, but nowhere near good enough to replace it. Social media is a bit like spun sugar, it briefly tastes like you are eating something, but ultimately the experience is fleeting and leaves you empty.

I wouldn't go quite that far. I wouldn't be doing nearly as well as I am without my friends online, who live everywhere from the next city over to another continent. They're a huge part of my life and I'd feel empty without them. However, I do need physical contact with people at least a couple of times a week - mostly in the form of touch, personally. I couldn't cope with being around people offline as much as I can with those same people online, though.
