Gatekeepers and web sites

I am interested in knowing which sites are acting a gatekeepers on 9/11 Truth. I just finished reading an article and comments on Buzzflash: "An Appeal to 9/11 Conspiracy Buffs" from Thu, 02/22/2007 - A BUZZFLASH GUEST CONTRIBUTION by Peter Michaelson. It was a pretty lame hit piece. The bulk of the comments were from sensible people familiar with the issues. One apparent troll continually brought in absurd arguments.

I went look for article to 9/11 Truth on Buzzflash, to see if they had ever published anything. The may have published some favorable articles, but this piece by Peter Michaelson took the cake for garbage.

So, are there any authors out there who are aware of sites that refuse all pro-9/11 Truth pieces? I know about Counterpunch. Some seem to allow 9/11 Truth comments, but no articles. GNN has links to a site that attempts to debunk 9/11 research, and a site that supports it. That is odd. Perhaps someone's idea of being fair and balanced?

What have you observed? I am most concerned with sites that are influential, that have a large readership. I have the germ of an idea that this information may be useful to us.
