If your company is struggling with trying to figure out what Tumblr is, or if you're wondering what your teen-ager is up to when you're still trying to figure out Facebook, then this handy video might help.
I use Tumblr to find content (it's still pretty good at finding new content like movie trailers or other videos for this blog), so scrolling through all of this other stuff (if you thought the Benedict Cumberbatch stuff was odd, take a look at all of the Avengers fan artwork) can be a drag. But once again, College Humor hits the nail on the head with this parody.
