blubbr: quizzes from youtube clips

blubbr is a site I learned about today from Danny Nicholson's blog The Whiteboard Blog.  At blubbr, you can play quizzes or create your own where a YouTube clip is played, and then a question is asked.    These quizzes are called trivs, and many of them are broken into categories, including Education.  Creating my own triv was quite simple.  Try you hand at the triv I created about the 1960's.
