Compulsive blogger Robert Scoble has a recent post about how his use of Twitter differs so greatly from the average user. Example:
7. The Twitter question is “what are we doing?” It’s NOT “what do you think about XXXX?” I break this rule all the time cause, well, I have opinions and Twitter is my way of sharing short opinions with the world. Sue me.
This is what Dave Winer means when he says people often "discuss Twitter ... as if there were a common user experience, but this is a misperception".
Most insightful, in my opinion, is Scoble's commenter Kelly:
I disagree. There is 1 rule of Twitter: Do whatever you want and if people don’t like it they can stop following you.
Exactly! That's the beauty of it: Twitter provides a format so limited in one sense (its simplicity) that it frees us to do some pretty interesting things with it.
Blogging? Social networking? Chat room? RSS reader? All of the above.
