Social Networking: The Present

Editor's note : This is the second of a three-part guest post by venture capitalist Mark Suster of GRP Partners on "Social Networking: The Past, Present, And Future." Read Part I first. Social Networking in Web 2.0: Plaxo & LinkedIn Next began the era of "spam-based" networks of which Plaxo (founded in 2002) was the king. Co-founded by Sean Parker (yes, the same one who worked with Mark Zuckerberg in the early days of Facebook), it encouraged groups of people to email everybody in their email address books and "connect" on Plaxo so that when any of their contact information was changed online it could by synchronized with everybody's local computer version and thus we could all stay in touch. There was a backlash against the Plaxo spamming yet it paved the way for everybody who came after them to get users to drive viral adoption and we'd throw up our arms and say, "oh boy, here goes another social network that my friends are going to spam me about" mentality that made it acceptable for everybody who came afterward.
