First for some good news: the United States still has a debt rating of AAA, according to Moody’s. However, it’s probably in the country’s best interest to keep an eye on increasing deficits before they get too large. That’s what the site I’m linking you today helps you do – keep an eye on the real time US deficit, and some of the unfunded liabilities on the books. I present: the U.S. Debt Clock.
Of note are the well-placed fields which divide various measures into burden per capita. Very nice. Here’s a static screenshot I took today at 5:11 PM PST:

Have fun with it!
