Has social networking killed domains?

Is the domainer dead? Is the business of buying domains for traffic and investment dead and buried?

Could it be that we are moving more and more towards a less open web, dominated by big names such as Facebook, Amazon and Google? These huge properties obviate the need to step off into the wild web and type in domains like we did “back in the day”. Now the url bar seems to be there only for cosmetic purposes. Even for well known properties online, users are getting there via search.
