Hi Noah and Alex,

 > Would it be easy/reasonable/in-the-spirit-of-the-thing to extend it 
start gathering statistics on JSON, XML, various forms of RDF, RDF-a, etc?

Some deployment statistics for RDFa are provided by 
http://www.webdatacommons.org/

The project does not use a browser plug-in for gathering the statistics, 
but extracts RDFa as well as Microdata and Microformats from the 
CommonCrawl, a large publicly available web crawl.

Detailed statistics from the last extraction (Mid 2012, 3 billion HTML 
pages) are found at

http://www.webdatacommons.org/2012-08/stats/stats.html

HTML pages are included into the CommonCrawl based on their PageRank. 
Thus the crawl is likely to cover the popular part of the Web, but 
things get sparse on the less interlinked sites.

As  meaningless with its browser-extension based data collection 
approach might also cover such pages, I think it will be interesting to 
see whether the statistics from both projects will point into the same 
direction. As far as I can see, they currently do to a large extent :-)

Cheers,

Chris
