Alexa vs. Technorati: charting the top Society, Culture, and Recreation blogs

The apparent outliers in the chart for Society, Culture and Recreation blogs shows some agreement amongst highly trafficked blogs.

PostSecret, dooce, and Overheard in New York do relatively better with links than traffic. Like others, perhaps these blogs have a core set of readers that are big linkers?

Can you explain any of the other points on this chart?
