According to the Getty Museum site, users can connect with the museum through its blog, YouTube, Facebook, Flickr, Pinterest, Twitter, Tumblr, Art Babble, Whyville and e-newsletters.  The usual "+share" icon is at the bottom of each page to share content with over 300 other applications.  The site did not mention a social media policy, but I found a Twitter Evaluation done by the Getty. This is an insightful document into how a museum evaluates its use of social media to reach its audiences.
