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.
