Zuckerberg's 19-Day Poke

A story about Mark Zuckerberg's hands-on response to the Snapchat threat.

"When Snapchat came out, Zuck recognized the threat very early on and created Facebook Poke. He literally wrote code into Facebook Poke - their competitor. They released it in either 9 days or 19 days, something ridiculous. He was one of the lead engineers actually writing code in the project. He doesn't normally do that, but that was the story at least."
