Does Google even have a social networking site yet? Seems unfair to compare what already exists to what might be the gleam in an executive's eye.
I think Facebook has shown themselves to be irresponsible and completely uninterested in their customers -- just look at how they handle privacy settings. They seem to do whatever works best for them, customers be damned.
Google, so far, seems to be fairly balanced in this respect. They incorporate what people are looking for, try to make things work better for the customer, and sure they collect and use things like page visits and search results, but they are quite honest about it. Google is like an honest politician: they still do questionable things, but at least they are honest about it.
