A Long Tale on the Value of Blogging

Excuse the pun but I recently came across a paper co-written by some IBM and Google researchers on the connection between blogging and the sales of products. The paper was written back in 2005 so is not new but it is one of only a few papers I've ever seen that have tried to draw a clear link between the impact of blogs on the sales of companies. The good news for bloggers is that there appears to be a connection. At least there was when it was written. While rather academic it is worth a read.
