Absolutely correct there about Facebook being the primary destination to find Facebook friends. Point I am trying to make is that Facebook being open to being indexed by Google also contributes to Google's growth. Searching for most names on Google throws up first results from Facebook, which makes it one more reason why I'll search for a name on Google than the situation where Google would not have the results on the what is probably the most authoritative page for most people. Thus, in the latter case, creating a situation where I am forced to use Facebook at the cost of Google. Edit: I think there is a popular zero sum perspective to these things, which is not necessarily true when you look at it closely.
