Just stumbled across this, but this is a great weekly column that fills in the blanks on the most recent episode:

It's a column geared for show watchers so it generally avoids future spoilers, but the writer looks to be pretty liberal in what he considers a "spoiler." I'm posting it here even though most of you already probably know this stuff, but I'm finding that even as a book reader there are some nice refreshers in here.
