What if I said, for the sake of argument, that the lifecycle of the average Facebook user is two years? Two years covers the 6 months of the novelty of Friend list-building, another 12 months of the novelty of commenting and sharing and trying to be clever with status updates, and another 6 months of messing around with apps like FarmTown? Then, at around that two-year mark, you realize that this is all a waste of time, that you don’t communicate with 90% of the people on your friend list, and you go back to emailing, texting and (gasp!) calling the people you actually want to keep in touch with.
A two-year lifecycle for Facebook would mean that by the end of 2010, a huge percentage of Facebook users would start to trail off. And then in 2011, another massive percentage will follow suit. (I’m not saying they’ll delete their accounts or won’t check in now and then. I simply mean they will cease to be “active users” the way they once were.)
Just throwing this out as a what-if. We seem to believe that, because Facebook is the size of a nation, that it has the stability of one. But the viewing audience of American Idol has been the size of its own nation in the past too — with just as much hype and chatter and addiction surrounding it. But predictably, American Idol is fading. It’s not going away yet, but it’s imaginable.
I’m not suggesting that Facebook is going away either. But to me, it’s reminding me of the neighborhood pub that’s lost its charm. What was once a simple, quiet place to hang out with friends has become a sea of bathroom ads, pinball machines and bar fights. You can still get a drink and enjoy a conversation, but you have to dodge a lot of crap to do it.
