Suzanne on Authority

Suzanne has started, on her Bookshelf blog, what promises to be a new series on Authority. Much of the post is a quotation from Luther showing that all Christians have authority, indeed "all are truly priests, bishops, and popes", on the basis of their baptism. And since baptism is not dependent on gender, nor should Christian authority be. This is certainly a helpful post. My main question is, why did Suzanne post it on her blog and not (as she has been invited to) here at Complegalitarian?
