So I know that the BEA has been trying to snazz up its site recently and some bells and whistles. There is even a flash/silverlight/HTML5 interactive thingy, where you can swap in out and out data.
FRED has an old clinks and text interface but now we have 837 new series on population and employment.
I have to jump off the bus right now. But later today I will show you how deep the rabbit hole goes.
