"Our country needs more companies like a LivingSocial," says Steve Case, chairman and CEO of Revolution, about the e-commerce site, known for its daily deals. Revolution Ventures, its venture arm, invests in LivingSocial, one of Groupon Inc.'s biggest competitors. When asked if he was concerned about LivingSocial's profitability and sustainability, Case says he's "very optimistic." Case, who rose to prominence as a co-founder of AOL, is also optimistic about social commerce in general. Says Case, we're "in the early stage of the evolution of this whole social commerce space. Companies like Amazon were the first generation of e-commerce. Companies like LivingSocial are the second generation."
