Very succinct. Concur completely. Flash has its place (video, games; both of which HTML5 are catching quickly up to). Its place isn't in making an entire, un-navigable, un-deep-linkable, animation-heavy site that takes me ten minutes to figure out how to use.
One of the comments on there said, "but check out thewfa! You can't make THOSE websites in html5!"
And my immediate, lizard brain response was: "Why would I want to? I bet their bounce rates are through the roof, and their return traffic approaches nil."
