Google co-founder Sergey Brin said today that it was probably a mistake for him to have worked on Google+ because hes not a very social person. Speaking at Recodes Code Conference, Brin — who also called himself kind of a weirdo — acknowledged that he used Google+ to post pictures of his kids to his family, but suggested that any previous professional focus on the social network was misguided. Brin, who co-founded Google with Larry Page in 1998, said his attention is now on his companys semi-secret skunkworks group, Google X. Google X is working on a range of projects, including a contact lens that measures glucose, in addition to augmented reality wearable device Google Glass.
