You're not honestly suggesting that developers start using flash to render their body content, are you?
Besides the copy/paste argument that people have already mentioned (yes, I know there is a "solution"). It's also inaccessible, takes longer to render and relies on a 3rd party product to render your website how you intended.
I know you'll probably say "give search engines and accessible-concerned folks a text version", but who honestly wants to maintain two different sets of code for ALL body content? And all just so the text looks a little better? Why not just tell everybody to use Safari/Mac?
