RockMelt is a browser for Windows and Mac that integrates Facebook and Twitter into your browsing experience. It’s fast, stable, and looks great, due to being based on Google’s Chrome. If you’re a heavy social network/media user it’s absolutely great.
RockMelt is in beta, and available through invite only, although the developer seems to be rolling them out quite quickly at the moment. Despite the beta status, it feels like a finished product, with only the tiniest issues to iron out. Head over to the RockMelt site to sign up, and check out my full review here.
