How to Think About... is a video series that provides you with quick frames for thinking about world's blizzard of technologies and services. The idea is simple: imagine we're having a beer and you ask me, "What do you think about Facebook and Twitter?" I switch on the camera and respond. These videos are informal, extemporaneous affairs and we hope they feel like the start of a talk. We'd love to hear how you think about these things, too.

We want to hear what you think about this article. Submit a letter to the editor or write to letters@theatlantic.com.
