Daily Kos is a blogging platform created by Markos Moulitsas, a former US Army soldier. It focuses on issues of interest to American Progressives.
The front page features news about American politics. Its viewpoint is usually from a Keynesian social democratic position so it's just as harsh on Barack Obama as it is on conservative politicians.
Readers can open an account and contribute to the site. Daily Kos accepts posts on virtually any topic.
 Other stuff
Every year, Daily Kos hosts Netroots Nation, a convention for progressives. It features presentations, panels and guests ranging from politicians to economists to bloggers. In addition, it is a member of Act Blue which helps to fundraise for progressively-minded candidates (and one data aggregator).
