However, unless Scott has another blog as well as http://weblogs.asp.net/scottgu I don't think he could be described as "one of Microsoft's most prolific technical bloggers". Perhaps in the past, but certainly not now. His blogs are always informative and useful but the frequency is pretty low compared to other Microsoft bloggers. No doubt because he is extremely busy getting the stuff that we need released.
Praise where it is due. Channel 9 is a great resource and I hope it continues to grow but it shouldn't become sycophantic towards those that provide the products.
