When you read a book, watch tv, or consume other type of media, you do it for a purpose. Most of the time the purpose is to entertain yourself. But on the web, specially on so called social media like Twitter, the purpose is constantly being challenged and shifted. It’s a two way, or asynchronous conversation as it has been proselytized, but you still have to manage that expectation. To listen or to talk, to participate or to follow, to write or to read. This is theoretically great, but you will never have that sense of completion I was talking about. It’s an open loop that never closes in your head.
