Do those sites need to be indexed, though? Web applications? Games? What is lost if a newspaper's animated pie charts are not indexed for search? I see more assertions in this thread that some websites need javascript, but does the javascript mediated content really add something for search? And if it does, is it perhaps content that actually ought not to have been mediated by js?
