I guess I'm also surprised to see a man with such an extensive Pinterest page. I don't know any men even interested in it (though I'm sure they exist. Just personal experience). It just seems strange in conjunction with KP's statement about not using social media.
IMO, KP is being truth about not using SM. Pinterest is a virtual bookmarking tool or bulletin board where members save ideas to their own account. According to it's CEO, it isn't a social network, nor was it created to be. MOO and BBM.
CEO Ben Silbermann says Pinterest is not a social network. The reason: when you're using the popular service to "pin" or save stuff, you're doing it for yourself, not others.
