Palo Alto-based Facebook rolled out a new look and feel to the firm's web site today, saying that the new design was focused on providing a new, cleaner, and simpler design. The site said that it will provide access to both the new and current versions of the site, with access to be limited over the next few days. Major features of the upgrades include ability to comment on stories and friends updates, upgrades to the Wall tab, new navigation, and privacy controls.
