Zuckerberg said he believes that the Groups feature will be a hit with users. The original Groups feature had limited engagement, but Zuckerberg simply believes the new version of Groups is “fun.” The new one, focused around Group Chat, shared networks and notifications, definitely has a deeper array of engagement tools — but will users adopt them into their daily routines? “I wouldn’t be surprised if only 5% or 10% create groups,” he said. Still, he noted that’s 25 to 50 million people — not a small number by any standard.
The power of Groups though, in Zuckerberg’s mind, is that the 5% to 10% that do actually create groups will invite their friends and help define these subsets of the social graph. Being part of a group gives these users access to its notifications, which should drive up engagement and make Groups into something many people will use.
