Graphs are made of nodes and edges. In SEO nodes are webpages and edges, links directed to them from other webpages on the graph.

I can emphasize with Tom Wolfe’s anti-intelectuallism and criticism of the art world. I tolerate his white suits too. I do hate however his inventing the use of present tense in profile articles (upon Ben Yagoda).

I read The Bonfire of the Vanities with the hope of remembering the 80’s. The noughties explain better what is going on nowadays that probably the 90’s do. For instance, the inability of Sherman McCoy to explain his job is bizarrely contemporary.
