Two reports of interest appeared on the Internet recently.
The first is a report from the Chicago Council on Global Affairs called "Engaging Religious Communities Abroad: A New Imperative for U.S. Foreign Policy." It is a bit long, so you might want to just read the executive summary at the beginning.
The second is a report called "The New Landscape of the Religion Blogosphere" by the Social Science Research Council. Unfortunately, this blog did not make it into the report. What an oversight!
