Facebook just installed its VP of Internet.org as the new head of WhatsApp after its CEO Jan Koum left the company. And now Facebook is expanding its mission to get people into “meaningful” groups to WhatsApp. Today, WhatsApp launched a slew of new features for Groups on iOS and Android that let admins set a description for their community and decide who can change the Groups settings. Meanwhile, users will be able to get a Group catch up that shows messages they were mentioned in, and search for people in the group.
