At this point, you've got a video up and playing on your page, but before we move

A little Webville good video
etiquette: the autoplay attribute
While autoplay may be the best thing for sites like YouTube
and Vimeo (or WebvilleTV, for that matter), think twice
before setting it in your <video> element. Often, users want
to participate in the decision of whether or not video is
played when they load your page.
