Apple has given a new look to the support section of their site, MacGeneration notes. The new theme ditches the Aqua interface for a more darker, structured look that evokes Mac OS X Lion.
The top right of the page which lists information about the article also sees the introduction of new sharing options via Facebook or Twitter.
The update is currently only visible on the US Apple Support site, but you would expect that they transition the other international support sites to the new theme within the next few hours/days.
