The most recent article, "Monastic lineages and the Vinaya: Which is Buddhist?" by Kester Ratcliff, The Buddhist Channel, Nov 10, 2009, was nearest to my heart.
It was an excellent review of various issues, with all the details and important references, I would expect from an informed position. I really appreciated the article! I hope it inspires more discussion regarding established Traditions and Buddhism, as American Buddhism tries to make that distinction moving forward.
I know from reading various blogs that many Buddhist read and follow your site! Keep up the good work!
