Facebook isn't taking over the world. It's already done it — quietly, while everyone was still arguing about whether MySpace was a fad.
The site crossed 400 million active users this month. At that scale Facebook is now larger than the population of any country except China and India. It is the third-largest "place" in the world, and the only one of the three with a profit motive, a CEO under thirty, and the ability to push a feature change to its entire population in a single afternoon.
The question is no longer whether Facebook is taking over the world. The question is what kind of world is being built inside it.
The four shifts already in motion
One — identity is moving onto the platform. Facebook Connect lets users sign into third-party sites and applications with their Facebook credentials. The practical effect: Facebook is becoming the authentication layer for the consumer web. Other companies have tried to own that layer. None at this scale. None with this much real-name data attached.
Two — the news cycle is moving onto the platform. Major publishers are watching steadily more of their referral traffic come from Facebook rather than from Google. Articles spread through friend networks rather than through search. That changes which stories rise and which die — and it changes who decides.
Three — advertising is moving onto the platform. Facebook's ad business is now built on the most detailed demographic targeting any consumer-facing platform has ever offered. Brands can target by age, geography, employer, relationship status, music taste, and interests — at a granularity that traditional display advertising never approached. The data is voluntary. The targeting is precise. The CPMs are still cheap.
Four — consumer behavior is moving onto the platform. Photos, events, group communications, brand pages, customer service complaints, political organizing, dating — everything is migrating into the news feed. The browser tab that used to be open to AOL is now open to Facebook. The phone screen that used to show text messages now shows Facebook notifications. The behavioral substitution is happening fast.
The PR consequence
Every consumer brand is now a Facebook brand whether it wants to be or not. The fan page is the new corporate front door. The wall comment is the new customer-service inbox. The viral video is the new press release.
Companies that still treat Facebook as an experimental channel — somewhere a junior person posts updates between higher-priority tasks — are losing the conversation about their own brand to the customers, critics, and competitors who treat the platform as a primary one.
Three operating realities every communications team should have absorbed by now:
The fan page is a publishing operation. It requires editorial, scheduling, response discipline, and crisis protocols. Treating it as a marketing afterthought guarantees that an angry customer or a viral video will define the brand's presence there before the brand does.
Negative comments live forever. A complaint on a fan page is indexed, searchable, and visible to every future visitor. The response to it — speed, tone, substance — is part of the brand's permanent record.
The platform's rules change without notice. News feed algorithm changes, privacy default changes, advertising policy changes — all roll out without consultation. Brands that build their customer relationship on top of Facebook are renting the relationship, not owning it.
What the privacy questions mean
Facebook's privacy controls have become more permissive with each redesign — defaults that used to be friends-only are now public, defaults that used to require opt-in are now opt-out. The trend is consistent and intentional. The company's commercial interest is in the data being more visible, not less. Users notice in waves, complain in cycles, and adjust their behavior temporarily before drifting back.
The unresolved question is what happens the first time the privacy story breaks badly. The fan page that's harmless today is the data trail that's awkward tomorrow. The "I like" button that brands are sprinkling across the web is a permanent declaration of preference that lives outside the user's control. Some part of that trail is going to detonate, in public, with consequences that no current PR playbook fully anticipates.
Where this leaves us
The "is Facebook taking over the world" question was the right one to ask in 2007 and 2008. By 2010 it is the wrong question. Facebook is now infrastructure — for identity, for news, for advertising, and for the daily routine of close to half a billion people. The right questions are different ones.
Who governs the infrastructure when it is owned by a single company under thirty-year-old leadership? What happens to user data when the business model requires it to be steadily more accessible? What happens to the news ecosystem when a platform with no editorial responsibility becomes the primary distribution channel for editorial content? And what happens when the next platform — and there will be one — wants to do what Facebook is doing now, except with even less restraint?
None of those questions have good answers yet. All of them deserve to be on the table.
