Sort of.  More than they used to.  But there’s still a big disconnect in the Canon.  This is a smart review, though, that shows it might be changing:

Great Literary American Novel Syndrome is a surprisingly persistent condition, despite the increasingly obvious likelihood that no work of art can sum up a nation as heterogeneous as ours without neglecting somebody. And in the end, critical reputation might become a moot point; substantive book reviews are a vanishing phenomenon, and the guardians of the citadel are fading away on every front. The last generation of old-fashioned androcentric Great American Novel practitioners will die out with Philip Roth; it’s difficult to picture a new version of that crew gaining a foothold in a marketplace where the vast majority of those who buy and read fiction are now women. Furthermore, in my (admittedly limited and anecdotal) experience, literary men under 45 are as likely to idolize Joan Didion or Flannery O’Connor as Norman Mailer or John Updike.
