Close of Business is a new video series that we're trying out. The idea is simple: at 5 p.m. (or thereabouts), we post a quick video summarizing the top three news stories of the day -- and give you one new Twitter or Tumblr to follow. Some of them we'll have written about; others will just be what people were talking about on the Internet.

Your Tumblr account of the day: HungoverOwls.Tumblr.com.
