I met a webmaster recently who runs sites that effectively 'scrape' to provide a service. He said he loves microformats as it makes it so much less time-consuming to code the scrape elements of his system. He likened it to XML in it's standardisation.
that pretty much sums up my email conversations with google. they look at my rich snippets, and ask me to make changes so its easier for them to grab it.
