Matt Haughey wrote an essay called Why I love Twitter and barely tolerate Facebook.
There's no memory at Twitter: everything is fleeting. Though that concept may seem daunting to some (archivists, I feel your pain), it also means the content in my feed is an endless stream of new information, either comments on what is happening right now or thoughts about the future. One of the reasons I loved the Internet when I first discovered it in the mid-1990s was that it was a clean slate, a place that welcomed all regardless of your past as you wrote your new life story; where you'd only be judged on your words and your art and your photos going forward.
Facebook is mired in the past.
One of my favorite posts on street photographer Scott Schuman's blog, The Sartorialist, consists of two photos of the same woman taken several months apart.
Schuman asked the woman how she was able to create such a dramatic change:
Actually the line that I think was the most telling but that she said like a throw-away qualifier was "I didn't know anyone in New York when I moved here..."
I think that is such a huge factor. To move to a city where you are not afraid to try something new because all the people that labeled who THEY think you are (parents, childhood friends) are not their to say "that's not you" or "you've changed". Well, maybe that person didn't change but finally became who they really are. I totally relate to this as a fellow Midwesterner even though my changes were not as quick or as dramatic.
I bet if you ask most people what keeps them from being who they really want to be (at least stylistically or maybe even more), the answer would not be money but the fear of peer pressure -- fear of embarrassing themselves in front of a group of people that they might not actually even like anyway.
For a certain type of person, changing oneself might be one of the best ways of feeling free and in control of one's own destiny. And in the social media world, Twitter feels like continually moving to NYC without knowing anyone whereas Facebook feels like you're living in your hometown and hanging with everyone you went to high school with. Twitter's we're-all-here-in-the-moment thing that Matt talks about is what makes it possible for people to continually reinvent themselves on Twitter. You don't have any of that Facebook baggage, the peer pressure from a lifetime of friends, holding you back. You are who your last dozen tweets say you are. And what a feeling of freedom that is.
