Right?
Well, looky here:

Look at the growth broken down by "Current Enrollment," at the bottom of the chart. Turns out, kids of all ages dislike having their parents and grandparents commenting on photos of an evening spent bar hopping, or reading their "wall," or, God forbid, friending their friends. In it's effort to be all inclusive, Facebook might have alienated the demographic on which it built its business. And if the kids leave, will the parents stick around?
We've often worked with retail clients who are convinced the only way to grow their business is to please everybody they can possibly reach. But that's just not possible. If you try to be everything to everybody, you're going to wind up spread too thin and you risk losing any kind of discernable identity. Our favorite retail marketing strategy is to identify a client's key strengths, and directly target the consumers who'd be most interested in those strengths. Why direct your retail advertising toward consumers who, based on their needs and preferences, really wouldn't chose your store over the one they already prefer?
In their bid to appeal to everyone, Facebook may see a new startup do to them what they did to MySpace not long ago. Sometimes, it's best not to please everybody, as long as you can be okay with that.
