Make a Free/Busy Schedule with Google Calendar and JSON

Ben Maurer has devised a simple JavaScript that will create a free/busy schedule using Google Calendar and JSON. This is perfect if you want to publicly make your schedule available while only giving details on whether you are free or busy. This mimics some of the functionality that you find in Outlook of course, but I think people are going to like this alternative, primarily because so many people do not have Outlook installed on their Mac laptops. A free/busy schedule application like this has crossed my mind several times and I applaud Maurer for going forward and developing it. I predict he sees huge interest in it.
