RockMelt Revamps the Web Browser for Social MediaHow the startup gained a new generation of users for its cloud-based web browser.

In the nine months after its public beta in March 2011,RockMelt, a cloud-based web browser, picked up more than 1 million users and made two reassuring discoveries: Some two-thirds of users were younger than 25, and people were using the personalized browser on multiple computers, iPads and iPhones. "This tells us we've made the first browser for the mobile, social media generation," says CEO Eric Vishria.
