2004: I sign up for Facebook because it lets me easily find classmates' cell numbers, and I got my first cell phone for Christmas!
2005: wow, my HS friends are all joining facebook! More connection.
2006: networks de-emphasized as facebook opens to anyone with an e-mail address. Many stop sharing contact info with a network, so odds I can find cells/emails go down.
2007: I graduate, but use Facebook messages to stay in touch with friends (feels less formal/weighty than email).
2008: I find some guy's wallet, find his facebook page, message him, and he gets it back.
2009: I'm using Facebook less. But Facebook stock is burning up. Everyone I know who went to work for Facebook could retire. I can't--but I apply to go back to school instead, which is a rough approximation.
2010: I really can't get much info on my new classmates from Facebook, except streams of status updates during class--a distraction, not real communication.
2011: I learn Facebook spams you a lot if you don't log in frequently enough (they need those monthly active numbers). Messages to strangers apparently don't work.
2012: What can I do on Facebook again?
