Dear God, no! It would be like MyLife acquired Google (forget about the money) and poisoned Goog search with their crap! Hope there is not enough money is Zucks pocket to pull something like that!

In the future, many of today's social network connections might just function as 1st person genealogical records (provided the companies can sustain).
