I believe HTML out there today will eventually be replaced by HTML 
carrying Rich Metadata that has been encoded using RDFa or  HTML5's 
microdata feature.

Thanks to RDFa (in particular) I can now hold conversations with SEO 
specialists about improving discoverability of Web pages via a few new 
HTML tag properties. This kind of  conversation simply couldn't happen 
12 months ago.

I don't believe people craft HTML by hand, the biggest impact is going 
to be with the generators of HTML who will be selfishly guided by 
optimal placement in the indexes of Yahoo! and Google, at first. The 
broader implications of the Web of Linked Data will follow from that 
point onwards.
