That's the problem with the downsides of social media. Even if you don't use Facebook, Twitter, and the like, their negative impacts still reach you through the people around and the rest of society. I suppose it's a bit like second hand smoke now that I think about it.

That said, the article makes what I think is an important point, that social media is not universally negative, it has some positive effects for some people. I usually use the word "cancer" to describe my attitude to Facebook and Twitter, and why I won't use it, but that is intentional hyperbole to stop further discussion.
