Attention Curve

The attention curve is a summary of who's watching what sources, and is especially applied to the blogosphere.

According to David Sifry who publishes regular reports on the Blogosphere, the following sections of the attention sphere can be distinguished:

- The Big Head: the most popular blogs

- The Long Tail: in a world of micromedia, the tail of the attention curve can stretch very, very far:

"the long tail of the blogging world goes out to 27.2 million blogs"

- The Magic Middle: sits in between the big head and the long tail: "these are blogs that are interesting, topical, and influential, and in some cases are radically changing the economics of trade publishing."
