Hmm. I didn't understand you to be speaking specifically about your family above; in fact, if you read it again I'm sure you can understand how it came across as a sweeping generalization that simply isn't true for the 2.3B users of Facebook (vs ~2B for Google).

Edit: wait, you aren't even the person I replied to. I think that person's point, although I disagree with it, is more relevant than yours, and I'd like to hear how they came to their conclusion.
