In five years, we may look back at Facebook as a has-been. But I am confident that it will enjoy a long life, at least relative to the Web. I don't care much for Facebook for my own personal enjoyment, but there's money to be made in Facebook. There are no doubt plenty of HN readers who can testify to this: huge amounts of money are being spent by companies around the world every day just to have tabs or full-blown Facebook apps developed for them. This amounts to a simple window (an iframe, really) within Facebook itself, but it is a gold mine for some of these companies, and they'll gladly pay to participate. Again, this may all dry up within the next few years. But AOL and Myspace never got close to this kind of user base, so the fall may not be so swift.
