What I find interesting about Facebook is that it allowed people from the current (and previous) generations to re-connect with people they'd lost touch with since previously there had been no tool designed to easily facilitate reconnecting. Future generations may find they they won't lose those connections since the tools will be in place allowing them to remain in touch as much or as little as they choose. Will they still have the same motivation to re-connect at some point in their lives if that opportunity has always been available to them? There's a very large percentage of Facebook users whose "friends" are really just people they knew back in high school that they connected with on Facebook out of curiosity. It'll be interesting to see if that dynamic continues for future generations.
