I wouldn't say it has no real value, I learned a thing or two, but that's about it. I agree though, it's not the most thorough resource, and doesn't even really approach the concept of n-tier.

George (and anyone else who is listening and is interested in development with SQL), watch the files section for a utility that I just uploaded that builds your SQL Server sprocs for you- if you are just getting started with SQL or even if you just do a heck of a lot of SQL development, it could really save you some time.
