Mobile web and mobile in-app behaviour are not binary. When users are in the facebook app, they spend a tremendous amount of time accessing the mobile web through facebook’s own in-app browser. The same for twitter and others. We enter social apps for discovery and then access the mobile web while still in-app. It is a mistake to conflate time spent on the mobile web with time spent in a traditional browser.
