Hey! Hey! Hey! Check it out! This is really neat! The first video here is probably just going to be the re-iteration of what you already know. It’s the founder of Twitter talking about what it is, how it started, and some of the possible implications  It’s an older video and its worth watching just to see how fast things have changed. The video that I really recommend watching is the second one. It is, to me, one of the best examples of DH. It’s fascinating, and it’s about how social media can, and is, changing the world. Both are only 8 minutes, and watching a video is easier than reading. If you have time for only one, watch the second!
