Facebook’s Buying

I have been seeing so many stories online about Facebook’s purchase of Instagram.  I thought a while ago that facebook would die.  It may happen someday, but not as quickly as I assumed.  Facebook’s buying and continuous innovations keep people coming back.  I can’t help but ask, is Facebook a new Google?  They both seem to go after every possible market.  Facebook has one leg up on Google though: The establishment as the premier social network.  This means that they can know their users better than Google, leading to better services.  Will Facebook try to reinvent our need and use of Google?
