Rockmelt had actually started out life as a "social web browser" based on Firefox and subsequently Chrome. The company pivoted a while back because it wasn't getting anywhere with that strategy, and has gotten into the world of news aggregation and discovery. The app is fast and looks nice, with a very Pinterest-y card layout (though Rockmelt calls them "tiles", because that makes it different.)
Although there are a lot of alternatives, Rockmelt's speed and design definitely help it to stand out. And, since the service is free and doesn't have ads, we think it should at least get a few minutes of a try-out to see if it suits your needs.
