What Should the New MAU Be? | Re/code: he simple explanation: The bulk of these four million people were not actually using Twitter. They were counted as part of a feature in the iPhone’s Safari Web browser that automatically pulled Twitter data whether the user was reading it or not. After the iOS 8 update, that automatic data collection was halted, and the people who were originally counted as “active” disappeared from the pot.
