Intel has launched its Centrino Duo Blogger Challenge with six bloggers -- including our own Mia -- and a "mystery blogger." Here's the premise:

On October 1, 2006 - Intel provided laptop machines with either the Core™ Duo or Core™ 2 Duo processor and built in Centrino wireless technology to 6 rising stars in the blogosphere. In return for these machines, our participating bloggers agreed to contribute to this group blog over the course of 5 weeks sharing their honest opinions and responses to a series of questions about blogging, the blogosphere and technology. Apart from recieving a laptop computer, none of these bloggers have been compensated in any way or asked to write anything specific about Intel. The aim of this blog is meant to stimulate discussion and bring bloggers together regardless of their “categories.”

The identity of the mystery blogger, described as "a person who many believe may just have defined the entire category of blogging itself," will be revealed on November 15th.
