Facebook really has revolutionized the way young people communicate, and as an 18-year-old, it is very hard to stay socially connected without it. I don't think Zuckerburg is evil, although the amount of power he holds would insinuate that. Facebook can't just one day decide to obviously exploit its users because of how very well-connected it has made them. It's provided a tool through which to communicate and connect over mutual interests, and it's within their users mutual interest to keep Facebook free and with as little SPAM as possible. You see the eruption of anger and whining when something as simple as the layout changes, think of what would happen if those that use Facebook daily were to feel exploited? The balance is delicate.
Facebook wants to defeat Google? That's like a competition between a mosquito and world politics. It doesn't make sense. The arrogance of Facebook's leaders is insulting. I'm glad I deleted my account and have no intention of using that useless site again.
Sorry to burst the excitement bubble, but, I am pretty sure it's because they offer their services for free. I dare google or facebook to even suggest charging for the use of these services. Of course with a free and highly useful product they are going to beat other sites that have membership fees.
