To my knowledge the "web" editions (used them before, briefly) are just trimmed down fluff removed copies. They're built specifically for serving web content and don't have quite as many services and features installed as you would expect from a server meant to be say, an AD domain. I may be slightly off here, but this was my understanding of it.
