Out of curiosity: who is processing the tag? And what does this have to 
do with SEO? Do search engines do anything with it?

 From HTML5's point of view the suggest replace is probably "<time 
pubdate>"... Did you look at that already?

Also: there seems to be overlap with Dublin Core's "dc:created"?
