"We’ve recently embarked on an exciting project to create some new “editions” of Flock, which will appeal to people that share strong passions for particular causes and topics.
We are launching our maiden “edition” today: the “Eco-Edition” of the Flock browser, which delivers the best environmentally conscious “green” content and media available from around the web in a tightly organized format, all available from a single download.
Once the browser installs, it updates with fresh eco-content daily in the form of news feeds, media streams, and favorite sites, delivering an experience that is dynamic, connected and always fresh. We’ve included an extensive offering of content topics, and fully expect people to prune and further refine the experience to better serve their own preferences once they’ve gotten acquainted with Flock."
