I enjoyed this Times article by Katie Roiphe about the sex scenes in the Roth/Mailer generations vs. the ones in the Eggers/Chabon times. That's one of the things I like least about the novels of the newer contingent (although it's a little weird to group that writers that she does) -- their writing w/ regard to sex is so fucking hip and twee. The scene she describes in the Eggers is particularly eye-rolling.
That was one thing I like about Netherland though. These guys could learn so much from Alicia Erian. In fact I prefer her writing in nearly all respects, not just this one.
