I can’t say that I am avid reader of Vanity Fair or many
of the blogs they track but I thought this was a clever piece of visual design

I am a sucker for a quadrant chart and this one combines
categorization, mapping based on content type, attitude AND navigation to the
actual blog. It also told me something about my own tastes – I tend to
like earnest opinion-oriented blogs and have little time for the scurrilous. That
would officially make me boring to invite any party!
