Take a look at the following:
The author of this article lists "15 Books You Must Have If You Are Doing ASP.NET Web Development".
However, he fails to mention ASP.NET 2.0 Website Programming Problem Design Solution, even though his entire site is nearly an exact rip from TheBeerHouse.
He even re-uses most of Marco's graphics. In fact, he was even still using the beer mug graphics for article ratings until recently, which I always thought was kind of strange.
(Guess what? His site even has most of the same bugs from the BeerHouse too, like the Article title bug.)
This is still a very relevant book, much more so than several of the others mentioned. A shame he didn't see fit to include it in his list of "must-have" books.
