Open Left officially launched on Jul 9, 2007 by a couple MyDD bloggers Chris Bowers and Matt Stoller.
Excerpts from the MyDD posting
There will be a wide variety of progressive people and organizations posting content, some of whom will introduce themselves as we roll out many of our soon-to-be regular features this week. We have innovative new posting protocol, epitomized by the Right To Respond, where, in the interests of openness and a desire to foster more conversation among progressives, any progressive individual or organization we blog about in a front-page post will have the opportunity to respond with a front page post of their own.
With both Matt Stoller and myself, you can expect much of what we provided at MyDD, only expanded into other areas. Mike Lux will be able to provide a wealth of professional political experience and an inside viewpoint rarely seen in our previous work. Also, there will be more topics we write about both for an extended period of time and in great detail, rather than relying on singular posts and off-the-cuff analysis. We will write more about legislative policy, as well as strategy on how to pass progressive policy. Further, there will also a lot of talk about progressive culture and lifestyle, since there will never be a sustainable progressive governing majority in America unless that governing majority is accurately representing a more progressive America.New Establishment Rising?
