Neil deGrasse Tyson hosts an early Reddit video AMA

Reddit's Ask Me Anything videos are getting off to a very good start. The social site has just posted its first batch of these moving AMAs, and one of these stars none other than Neil deGrasse Tyson, the Hayden Planetarium director known for making astrophysics accessible to everyone. As you might guess, the video format gives deGrasse Tyson the opportunity to answer with the kind of depth and expressiveness that you don't get with a text reply. Among other things, he chooses the universe's best art (spoiler: it's not a painting) and explains why he doesn't like mind-altering substances.

There are only two other video AMAs, one featuring FiveThirtyEight's Nate Silver and the other revolving around actress Hilary Duff. However, you can expect to see many more videos from Reddit (including documentaries and user-made content) in the future. As the simultaneous Upvoted launch suggests, Reddit is hoping to expand its horizons and generate money from more than just the ads next to your comments.
