Given that the biggest obstacle to the adoption of microformats is the lack of programs that actually implement them, I have been toying with the idea of writing some useful programs that work with all the information we put onto our websites.
It's frustrating that we're at a point where the bottleneck of the Semantic Web ideal is not actually a low amount of structured information, but the lack of any program to do anything interesting whatsoever with it!
Who cares if we all use the HTML5 tag on our sites, if there is no browser that actually provides a "contact webmaster" button in the sidebar?
Who cares if we all mark up our cooking recipes as perfectly detailed machine readable h-recipe entries, if there is zero cooking apps or whatever actually capable of using any of the data we provide?
Who cares if we all use h-cards and h-feeds and whatnot if there is no feed reader that can actually notify us when our friends posted a new blog entry?
