why people tweet

It's a nation-wide mystery why people would bare the arbitrary 140-character limitation just so they can type every minutes of their life on a bulletin board where anyone can see (if they want to).

After watching the exaggerated version of it on the following Doonesbury comic, I got my own <140 character explanation:"We tweet, to leave a shared memory of our transient existence." It's the same reason people would leave graffiti (or gum arts) on random walls. The hope is whoever passes by will see it and realize that someone has been here. The only difference is that tweeting is legal and more convenient. You can do it anywhere and you don't need to carry cans of spray paint.





Proving one's existence is deeply rooted in one of the most fundamental element in Maslov's hierarchy of needs: safety.
What could be more reassuring that you are safe than the fact tens of millions of people can synchronize with your thoughts up to the very minute. Although that's an illusion, because the very action of tweeting could put a driver in danger.
