I have been collecting several sites on energy and the environment. These include blogs and media. The idea of having as many sites as possible is a very good idea. I believe you need to be as strong as possible and go as big as possible. Communicating through so much noise on the web requires generating as much interest as you can. Would you like the list posted on the forum or emailed to someone specific.
I also agree with the statement of having a story to go along with the announcement. This should be multi-part so that there are click-throughs.
