On that which is uninteresting.

I have nothing interesting to say. What would it mean if I did have? Would an objective appraisal of *interestingness*, or otherwise, be possible? If I did have something interesting to say why would I want to share it. Would the fact that I had shared it make it more or less interesting? If I had something interesting to say but refused to say it that would, I believe, be interesting in and of itself and what ever it was that I was choosing not to say would not have to compete with its own absence. So what is the drive the drives people to share what they think is interesting with others when by sharing it that have, to a certain degree, negated its interestingness.
