While I congratulate the Sparrow team on moving on to bigger and better projects at Google, one thing leaves a bad taste in my mouth: the fact that the Sparrow team is no longer free to build products for itself. When I last spoke at length with Sparrow founder Dom Leca, he told me about how he left a corporate app-developing world to build something he wanted to use. "To build a better mail," he'd say. Each day Leca and friend / colleague Dinh Viet Hoa set out to build an email app they'd want to use.
