At All Things Democrat
we just launched a new project ... a "Digg clone" with a focus on liberals and progressives called ATD - Reader Supported News
Like the old Buzzflash.net
(that closed when they became a part of Truthout), ATD focuses on post submissions from lefty blogs, forums and sites.
Users can submit articles directly or through their browser with our Bookmarklet tool. We also have several share button-links for bloggers to submit posts remotely.
Users can vote for articles, submit comments, and even vote on the comments.
So please check us out at ATD - ATD - Reader Supported News
