An epic showdown!
In this corner, we have Academic Earth. "Thousands of video lectures from the world's top scholars." Looks sharp. Looks keen. And you know it's good stuff because they didn't mess with the regular scholars, only the top scholars on this site, baby.
And in this corner, we have YouTube.edu. They have thousands of videos as well, but they've let in the rabble. Although you can't sneeze at the sheer number of schools they can boast. Plus, they have video from IITM, for pete's sake!
Who will win? Who will emerge victorious in this epic struggle?
Why, that's already been determined. You and I, my friend--we are the winners.
