I found this article really interesting. I started using Facebook in high school, back when high schoolers were to use hs.facebook.com to access Facebook and networks were heavily emphasized. I left Facebook about one year ago today.
One particular observation that the article makes that I want to flesh out a bit is the following: Facebook has grown and grown in terms of the size of the application itself, and it is clear that they have pushed very heavily for the 'platform' model. It seems like this is getting replaced by a series of more specialized, more mobile-centric social applications, like Snapchat and Tumblr. Of course FB owns Instagram so they have that going for them, but this does seem to hint at a bit of a growing trend in social networking.
