Candid, an anonymous-sharing app aiming for frank debate, launched Thursday, the brainchild of Google vet Bindu Reddy. Reddy, Candid's CEO and a former head of product for Google's social apps, said she embarked to create Candid after she felt unable to share unfiltered opinions on mainstream social networks. "My social media network includes everyone in my life, from friends I haven't seen since high school to family members and work colleagues. Expressing my opinion, especially about controversial issues, inevitably upsets someone," she said in a statement. "I needed a place to express myself and engage in discussions where ideas can be debated on their own merits instead of being used to attack me as a person."
