On the off chance that you're adding microformats to your site in good faith rather than just trying to make it accessible to google, there are non google tools, utilities, search engines, applications, browser extensions and so on that make use of the microformat data, to, for instance provide "add to calendar" buttons to marked up events, or automatically convert an html blog to an rss feed. I don't know if they ever got there but there was a vision to have a standard markup for shopping cart items so browser extensions could assist with price comparisons.
That's my point exactly, if you are adding microformats to your site in good faith because you believe it is the best thing for the web and enables peoples tools to work with your site better, google penalizes you by reducing your site traffic and increases their sites utility for users, effectively increasing their profits off of your labor while starving you at the same time.
i don’t know how your hosting plan works, but on every plan I’ve looked at, traffic costs money. if your web based business depends on traffic to serve advertising, then no, you’re not doing it in good faith to make the web better.
