From their home page, "Initially built for The Washington Post, Arc Publishing is a modern publishing system engineered to meet the needs of the world's largest publishers. Many of the foundational aspects of Arc are based on our experiences—what we liked, what frustrated us, and changes that we saw coming—with previous CMSs we had used ourselves." First encountered on the Washington Post's web site (no surprise there). Think of it as Word Press for the big boys and girls. Doesn't seem to have anything to do with tracking users. It's for publishing and maintaining large volumes of rapidly-changing content like newspapers and magazines would have.
