Earlier quoted context omitted.
Virginia -- particularly Charlottesville and Richmond -- is not some Southern stereotype. That being said, I think the people most interested in this news are those with vested interests in Virginia higher education -- alums, donors, etc. -- and that tends to raise the average level of discourse.
Most of the south isn't a southern stereotype. The DC metro is more like a new england city than either of the two you mentioned. This paper is based out of southeastern VA, in the VA Beach and Norfolk area.
That said, I'm surprised the comments are so cordial. I agree with the analysis that the fact that it's mostly UVa alums/students and interested parties commenting contributes to the higher level of discourse.
