Jon: I appreciate that you've taken the time to join the discussion, but I would like to point out two facts about the special feature that didn't notice, or chose not to mention:

1) One of the blogs does have female authors -- see my earlier comment
2) Three of the blogs have anonymous authors, whose gender is uncertain.

As I have stated before, the fact that several authors are female and others are of unknown gender did not did not impact their inclusion.
