How big is the Netflix webapp, though? There's what, 5 or 6 main content "views", then around 20 user-editable forms? Plus the help site. Am I viewing this incorrectly? It doesn't just doesn't feel like Netflix is a large app from the UI perspective - maybe that's just good design.
Hope this doesn't come off as "I could do this in a weekend", just questioning how big the actual webapp is.
