This website describes itself as "an Internet-based progressive news and grassroots activism organization, founded in 1997." It also says "We are a nonprofit, progressive, independent and nonpartisan organization." A perusal of its home page reveals that it is concerned with a broad range of social, environmental, and political issues, and that its coverage includes both news stories and commentaries.
At the time of my visit, there were front page articles about climate change, ocean pollution, persecution of Iraqi women, health care reform, governmental censorship of the internet, gay marriage, undeserved corporate salary bonuses, use of torture during interrogations of suspected terrorists, and protection of endangered species.
To visit this website, go to Common Dreams. The slant of the reporting is clearly liberal, although like many such sites, it prefers to use the word "progressive".
