weblogs.asp.net/ aliased to blogs.msdn.com/
I am sure many of you know this, but I recently told someone and they were surprised to learn that any Microsoft employee blogging on weblogs.asp.net can be accessed via blogs.msdn.com.
So for example..
http://weblogs.asp.net/cbrumme == http://blogs.msdn.com/cbrumme
Enjoy!
