Thanks for the feedback Chris!
I agree with the login stuff -- it's very confusing when presented on install -- what's logging on to what? I'd like to so MS clean the install up a bit on the next version. It's a deceptively complicated architecture -- I hope I brought that out a bit in this first article.
The web farm stuff is very misleading. I've got more on that coming. I wanted to approach this from a crawl-before-limp-before-walk-before-run kind of thing
