For once because I like to debate and I am interested in politics.
Second I wanna know how Americans tick - regarding politics - as politics is the about only thing that freaks me out about (US)Americans (well yeah environmental issues do too but that is closely related)

And finally maybe sometimes I can clear up common misconceptions about us - but usually noone wants to listen
It is a good source of info from very different sources
Oh and u know as foreigner I actively partake in enhancing cross cultural understanding

or entrenching
