The Washington Post announced today that Willamette Week has begun using its Arc content management system:

This is the first licensing client for The Post’s software-as-a-service arm, which was announced a year ago when it began experimenting with this new business by supporting the web infrastructure of student newspapers at Columbia, Yale and the University of Maryland.

“The best thing about the new site is its flexibility,” writes Lizzy Acker, Willamette Week‘s web editor:

Arc uses WordPress, but with what we can describe in layman’s terms as a flexible ubertheme that allows publishers to build any page from scratch, moving modules around with ease. Readers will notice the change starting with the dynamic front page, which can be frequently adapted to highlight content we think will be of most interest to readers at any given moment, and give every story exactly the amount of play it deserves.
