Entrepreneur and investorย Reid Hoffman has backed or helped build over 50 ventures, including groundbreaking companies likeย PayPal, Facebook, Groupon, Flickr, and of course professional networking juggernaut LinkedIn, which he co-founded. So what does one of the countryโ€™s most prolific investors think about the future of social networking, a phenomenon some say is already dying? โ€œWe are in the first inning,โ€ Hoffman says. โ€œPeople are still learning what does it mean to have these networks be a fundamental part of their life.โ€ Hoffman believes as people โ€œrealize the networked age,โ€ any number of possibilities for building new and evolving networksโ€”perhaps around sports, religion, and journalismโ€”will emerge. โ€œThereโ€™s a variety of still even fundamental social networks to be created,โ€ he says.
