One risk of trying to follow church disputes from blogs is the posturing, but the other risk is not seeing the long view. I offer up
Episcopal Dissidents, African Allies: The Anglican Communion and the Globalization of Dissent, a dissertation by Miranda K. Hassett, as something of a corrective. It's quite long, but as a totally secular and scholarly perspective on how this is playing out in the larger communion, it's quite valuable.
