I think a bigger difference with social media is going to be things like the impact Instagram will have for historians. For the longest time, we had no images of the past. And then when we had the advent of the camera, we had a record of the things people chose to photograph, which, for a while, were portraits of your family, a new building we built, or a really big horse. Well now we have images of everything. That will be the biggest difference I think - that we will have a visual record of this reality in a way that will be completely covered.
