No, I have no particular taste for CSV, though some people like it because you can open the files in Excel without any conversion. Personally I usually use data in code instead, and JSON is better there.
You might consider putting a link to these files in the page, unless you think it might become a big resource drain.
Do you really like CSV? If so, vote and i will build it. http://webnumbr.uservoice.com/forums/38506-general/suggestio...
