Flock is an RSS aggregator written in Java. It is a server-side web application accessible with a browser, similar in spirit to AmphetaDesk. [edit]
Though it's easy enough to change your browser's language to Spanish, using a browser that's customized specifically for a Hispanic audience is even better. The folks behind Flock, the Mozilla-based social Web-browser, have teamed up with Spanish-language media company Univision to develop the an exclusive edition of the browser that will provide content aimed specifically at Hispanic audiences.
The Flock browser is one of those things you either get right away or scratch your head and wonder why anyone would use it. It's not as visually clean as other browsers, but if you're steeped in social media or crazy about Flickr and YouTube then you'll love Flock the second you fire it up. It's also just the answer if you're tired of juggling dozens of apps, tabs, or windows to keep track of what's happening on Twitter and Facebook while watching a video of a cat playing piano and flipping through pictures of penguins.

According to Mike Arrington at TechCrunch, several sources say that the Mozilla-based "social" browser, Flock, will soon shed its Mozilla code base and start using Google's Chrome framework for future releases.
Flock's CEO, Shawn Hardin, responded to Arrington's post, saying that the browser's upcoming 2.1 release is being developed, and will be released with, its traditional Mozilla underpinnings. Hardin does not explicitly say that Flock will move to Chrome, only that the browser space has been "heating up" rapidly in the last few months, and that the Flock development team "will continue to make architectural decisions that balance what's best for our users and what's best for Flock as a business."
