The main theme seems to be an examination of Jefferson’s ideals in today’s world. There are articles on such inflammatory issues as race and politics (including one by Annette Gordon-Reed, author of the 2008 National Book Award Winner, The Hemmings of Monticello which we reported about here.). It looks like you can comment in these sections and add your 5 cents.
There is also a blog, a section on quotesgrouped by topic – which is quite handy), and my favorite part – a list of things named after TJ. Awards, Buildings, Species, Counties, Monuments, etc. It doesn’t seem quite complete (they do not, for example, list the 25 counties, 1 parish, 1 state capital, and 1 city named after Jefferson). They could have a lot more fun with this – maybe they will flesh it out over time.
