I'm paying 90% of my attention right now to a Windows Azure online training class. I already knew a lot of the material presented so far, but not all of it. It's like re-taking a class you took as an undergraduate; the 10% you didn't know is actually really helpful.
Like next week's class, which will go over Infrastructure as a service: a lot has changed in the last year, so it should be valuable.
Apparently, though, my homework is to build an Azure web site this week. Not a multi-tier application with a worker role. Just a web site. How adorable.
