““In Ads, we had completely failed to realize the importance of the logout page on FB. A bit of background: In most developing countries, people do not own desktop computers, and their phones are non-smartphone pieces of shit (this is, of course, gradually changing). So people do what you do as a Western backpacker in Brazil or India or whatever: they use an Internet café or other public computer. They log in, use Facebook at some rate per hour, and then log out. What they leave behind is the logout screen, which just so happens to be the most common webpage up on browsers in the world. Really. You walk into a library or café anywhere in the world, and most of the screens will be glowing Facebook blue. And that is also how most new Facebook users in these countries came into being, not to mention nudging existing users into using Facebook. A fact that we in Ads did not even begin to appreciate.””
