I've been wanting to write something about this site for a while now, but I've had a hard time figuring out what exactly to say about it beyond just describing what it is, who's involved, and what they do.
ArtBabble is more than just another collection of videos about art. Each video comes with a sidebar of notes and more information that the viewer can dive into in order to explore more aspects of what the video is presenting. At times this sidebar can be a distraction, and other times can lend more depth to something like an Art21 video about Jenny Holzer that you've seen a few times.
The bulk of the videos come from MoMA, SFMoMA, Art21, The Indianapolis Museum of Art, The Los Angeles County Museum of Art, The New York Public Library, and the Smithsonian. By and large, the content is geared towards the art novice, but there are some incredibly poignant videos for arts managers on the site, like the Museums and the Web 2009 video posted below.
So far my favorite video series has been the Behind the Scenes at the MoMA, but all of the videos I've watched are really high quality and very informative.
In an Update, last night ArtBabble won a Gold Muse award from the AAM for best online presence.
