To mark the launch of the new Facebook app Paper, Mark Zuckerberg has given a lengthy interview with Bloomberg Businessweek. Speaking about the company's Poke app, which was thought to be a Snapchat competitor but failed to make an impact, Zuckerberg dismisses the app as "more of a joke." Apparently unconcerned by Poke's poor performance, he explains that "a few people built it as a hackathon thing, and we made one release and then just kind of abandoned it and haven’t touched it since."
Elsewhere in the interview, Zuckerberg laments that Facebook's move to mobile was "not as quick as it should have been," despite the company recently announcing that more than half of its revenue comes from mobile advertising. The full interview discusses a wide range of topics and runs several pages long, so if you're interested in Zuckerberg's take on Facebook and the world, you can head to Bloomberg Businessweek to read the rest.
