Well, in fairness to you, I don't think it's either or. I think the content generally is important, but I don't think it's content alone (since we don't have a "laptop disease" problem) and it's not ONE piece of content (we don't have a "Facebook disease" problem). I also think that some of the issue is the ease that the smartphones allow us. Seriously. I'm not on Facebook or Twitter, and I'm conscious of having to address anything I write in real life, but I can tell you, having a smart phone could have gotten me into SERIOUS predicaments (not necessarily "trouble", but stuff I wouldn't share in mixed company) if I wasn't careful. It's just TOO easy, and too.... thrilling for lack of a better word.
If we're not careful, "smart phones" and "social media" will be the death knell for monogamy in our lifetime (again, not really kidding here).
