I am out of my league. Here are the people writing intelligently about this subject:
Her Bad Mother
Gingajoy, who is very educated in this topic
Under the Mad Hat: this is the link to the first of a series. A series! Funny and serious, and sometimes spot-on (and sometimes I disagree a bit, which I think would be okay with her).
BlogRhet, which is all about meta-blogging
I am sure there are more. Let me know what I’m missing.
