Much more than your arguments, I'm disappointed at the childish nature of the exchange. The questions are fruitful, but the name-calling and sudden antipathy towards Microsoft is ridiculous.
You may see yourself as a blogging authority or hot-shot, but that's not why I read your blog. I read you because you link to interesting discussions and products. Quite frankly, your blogging tone makes you sound like you blog so that you can play with the big kids.
Please don't let egocasting become the new trend on your blog. I'm glad you're moving onward.
