Social media existed before the iPhone/android. I remember needing to be at home on my computer to check myspace, xanga, and even thefacebook. Not sure how I feel about this article (it's interesting at least) but the existence of phones/apps does coincide with a lot of changes to our relationship with social media and a lot of changes to social media itself.

Perhaps without smartphones in everyone's pocket we would use social media much differently and that industry would have grown differently....
