Just so nobody misses a passing reference in the comments, I wanted to make this item a post of its own. Nigel Beale is hosting a "Hamlet roundtable" on Thursday of this week featuring four "prominent lit bloggers". I'm not really sure what prominent means in this case, but they are:
http://wutheringexpectations.blogspot.com/ (Amateur Reader)
http://fernham.blogspot.com (Anne Fernald)
http://www.sarahweinman.com/confessions/ (Confessions of an Idiosyncratic Mind)
http://www.edrants.com/ (Edward Champion's Filthy Habits)
They do each appear to reference Shakespeare frequently, although I'm sure how often they are writing specifically *about* Shakespeare. I think I may have linked the Idiosyncratic Mind one once or twice.
Anyway, sounds like it could be worth a watch. They do appear to be a fairly deep lot (at least, relative to this blog), so your mileage may vary.
