More Progressives and the Mission of this Site

In my view there is a rich diversity of smart and articulate conservatives on this site and that is one of its strengths. I think the site is also stocked with some outstanding progressives, but the posts on the site predominately come from conservatives. I think the site would better achieve its mission if more progressives were added. I think urging those progressives on the site to do more or post differently will help only at the margin (though they, including me, might be encouraged to post more if the site could sustain discussions of what Catholic progressives should think about various issues). Those on the site have other responsibilities, and, of course, post at different rates in different seasons. Below is the quantity of posts from members of the blog in the period from October through December. I think it supports my point, but I would be interested in arguments to the contrary particularly off line. I say off line because I am anxious to avoid public discussions of who is conservative or liberal and who is not.
