I've recently walked through the entire NerdDinner pdf and sample with the final ASP.NEt MVC build and am thoroughly impressed. Before I start touting it's awesomeness through within our dev group, I'd like to also know what some of the pitfalls or misuses of this new stack. Can I possibly get an outline or explanation of when not to use this?
