If you'd like a front row seat to some of the most compelling policy commentary in the United States, you may want to keep tabs on this useful blog from the Brookings Institution. Each weekday, different policy experts offer a bit of commentary on topics that include immigration policy, disaster preparedness, and the use of technology by the federal government. Visitors can comment on each entry, share the entry with friends and colleagues, and pass it along via their Twitter feed or other social media. The site also features past blog entries dating back to September 2009 and embedded links to other relevant Brookings Institution reports, working papers and briefs.
