Flock Refresh Trumps RockMelt
RockMelt was released in beta in November with the claim that it would bring social networking into the browser. But Flock has been a social networking oriented browser for years now and a new version shows where Flock has several advantages over RockMelt.
To a certain degree, Flock predates social networking. When it was first introduced five years ago, the company referred to their eponymous product as "The Web 2.0 Browser."
But over time, Flock has done a good job keeping up with changes in collaboration and social networking. With the newest release, Flock 3.5, the browser showcases a much broader support for social networking tools than the much newer RockMelt beta.
