What are you doing, WordPress.com?
My first thought is that stuff like this always leads to yet another "content churn" iteration, where even more user-authored stuff drops off the Internet, leaving behind an even more desolate wasteland of SEO spam and dead links.<p>We've lost so much already... the old Flash content, the GeoCities pages, the forums fallen under Facebook's iron curtain, the archives of obscure culture erased by copyright lawyers. The lit windows of the Internet that went dark, one by one, only to be replaced by gaudy commercial signage.
