Facebook’s eye-popping numbers need an asterisk

Facebook claims it has 845 million “monthly active users” and an even more incredible 483 million “daily active users,” but Andrew Ross Sorkin says “those eye-popping numbers should have an asterisk next to them” because of the social-media company’s “active user” definition.

Every time you press the “Like” button on NFL.com, for example, you’re an “active user” of Facebook. Perhaps you share a Twitter message on your Facebook account? That would make you an active Facebook user, too. Have you ever shared music on Spotify with a friend? You’re an active Facebook user.

Sorkin points out, though, that “Facebook’s definition of ‘active’ is nowhere near as problematic as Groupon’s fanciful accounting, and it does not appear that Facebook is trying to deceive investors.”
