I do care about metadata sometimes. It isn't my primary interest and  
I'm often skeptical of the cost/benefit ratio of metadata. I should  
point out that I don't in any way object to solving the problems that  
Microdata addresses, even though I'm personally more interested in  
solving other problems in the sphere of HTML.

As for how can I say whether my concerns are addressed:

An example of my concern about RDFa is that in uses syntax that in  
Gecko, WebKit and Presto parses to a different DOM Level 2  
representation in text/html and application/xhtml+xml. I can assess  
whether a proposal has this property even if the proposal is solving a  
problem I wouldn't personally pursue solving as a priority. This  
touches on my activities as a parser developer.

An example of my concern about Microformats is that they lack a  
precise processing model. Again, I can assess whether a proposal has a  
precise processing model even if the proposal is solving a problem I  
wouldn't personally pursue solving as a priority. This touches on my  
activities as a validator developer.

I used the word "evangelism" in this sense:

I'm not suggesting that Microdata is the best solution in the absolute  
sense. I'm just suggesting that it fixes some flaws that alternative  
solutions have, so it's better (or less bad). I encourage you to help  
the WG make Microdata even better.

It may well succeed as a stand-alone thing, but I choose not to  
support splitting it out merely in order to show confidence.
