President Obama's second inaugural speech was delivered only two days ago but is already being compared -- in ways positive and ways negative -- to past addresses given by chief executives.

Thanks to the Guardian newspaper and developer Santiago Ortiz, we have a very cool infographic that allows some of those comparisons.  Below you can look at the words used in every inaugural speech since Richard Nixon's in 1969 and, even better, compare how often particular words came up in each of the adresses over the past four decades.

It's an amazing tool. And, yes, we've already spent far too much time noodling around with it this morning. Enjoy!
