The Law of Online Sharing
Facebook's Mark Zuckerberg will eventually have to deal with the fact that all growth has limits. — The idea of limitless growth gives sleepless nights to environmentalists, but not to Facebook founder Mark Zuckerberg. He espouses a law of social sharing …
Context & Ripple Effects
The idea that Mark Zuckerberg runs Facebook on a 'law of social sharing' is not new to this beat: Rough Type framed Zuckerberg's Second Law back in November 2008, and the Los Angeles Times had already sketched the Facebook revolution a year before that. What changed by December 2011 is that the sharing curve is now being cashed in — Facebook confirmed it will start showing Sponsored Stories social ads directly in the main web news feed from January 2012, and rolled its Timeline profile out worldwide the same week.
The monetization push lands alongside a shift in where sharing happens: Facebook for Android passed the iPhone app in daily active users for the first time in mid-December 2011, after launching more than two years later. Technology Review's piece argues the premise of limitless growth will eventually collide with limits — a claim the company's own product calendar is about to test.
First-order effects
- From January 2012, every share a user makes becomes potential ad inventory inside the news feed itself, so Facebook's users start seeing their own activity sold back to them as Sponsored Stories.
- Page administrators gain a direct private-messaging channel to fans (initially Asia-only), giving brands a second way to convert the same social graph into outreach.
Second-order effects
- Advertisers get feed-native social proof at scale just as mobile usage overtakes desktop-era patterns on Android, pushing Facebook to design ad formats around small screens rather than the web feed alone.
- Rival networks face pressure to match both the format (ads woven into streams) and the messaging tools, since brands will gravitate to whichever platform turns fan relationships into revenue fastest.
Third-order effects
- If sharing growth does saturate, as Technology Review argues it must, the business model shifts from expanding reach to deepening monetization per user — more ad load per feed view — which is precisely the trade-off that invites user backlash and, eventually, regulator attention to how personal activity becomes commercial inventory.
- A pattern of turning user expression into distribution-layer advertising would make platforms like Facebook liable battlegrounds over consent and data use, structuring the next decade of social-network regulation.
The trend: Social networks are converting user sharing itself into monetizable ad inventory, testing whether engagement growth can keep outrunning the saturation limits critics have flagged since 2008.
