This is definitely right. Creation on Twitter isn't for everyone. It's confusing, convoluted and hard to use. Consuming Twitter is something almost everyone does unwittingly. New stories are generated there, celebrities post directly. It tears down walls between PR and the masses. It's a great service, but truly Twitter must give up on the idea that it's going to be able to get everyone or even a larger chunk of the population to actively send messages there -- it can't and won't.
