    Use Cases

Screen scrape microdata:

grab an ical event (send)
grab an hcard
atom feed
make note of an hreview (actually I can't think of what you'd do with an hreview)
? generic grabbing, or we specifically figure out support for particular kinds of data (i.e., microformats.org specs)

  Javascript is a funny thing.

  Here are two things that will hit you with requestAnimationFrame

  1) If you alias the window.requestAnimationFrame function on to anything other
     than a window object, you get an Illegal Invocation Error.

     You can solve this by using call() with the window object set.
