First up for my HTML5: A Story in Progress is Deprecated is now Obsolete.
It was an elegant process, for an elegant time. We gently pushed the no longer wanted attributes and elements over a hill and out of sight. We don’t have markup hills now, in HTML 5, we have markup cliffs. We haven’t taken attributes and elements over the hill, we’ve taken them to cliffs, and pushed them off. And the little buggers are grabbing hold of page designers and developers, not to mention authoring tools and user agents, to take with them on their way down.
