"100% Flash" is not that bad - I'm using FBSD at work and never bothered to configure flash plugin (it's possible! really!) so "100% Flash" sites are just completely under my radar. I think sites which use flash exclusively for navigation, as in top/left/right menu are worse. I can see those, but to be able to do anything (like go to other page!) I need to use google. Thankfully, I didn't see such a page in quite some time.
