Really Microdata is designed for humans first you say well thats news to me?

Itemscope, itemprop, itemref...etc..etc don't sound human friendly at 
all, If microdata were ever to become popular ( god forbid ) think of 
all gigabaytes of data that's going to take up just because you thought 
that pre-pending everything with "item" was somehow intuitive, and TBL 
worries about forward slashes, Im suprised you can sleep at night ;)

Thanks anyway to your chums at google for the usability testing... I 
read your changes almost as soon as they happened, you did tell them 
what microdata is supposed to do didn't you?

Why use microdata at all when microformats already exist,  I cant think 
of a single microdata use case that isn't already solved by microformats 
and RDFa, by the way microformats and RDFa work very niceley together on 
the same page, I would hate to try and mix micro data with microformats 
or RDFa

I have said this before I still don't think you will be landing any 
planes with microdata sorry.

Best wishes
