Been thinking of doing a mini-site of sorts. “Microformats That Work,” with real-life markup examples and tips ’n’ tricks. (I mean, there’s the wiki and I know I’m able to edit it, and DRY and such, but it is kind of hard to navigate.) Maybe that: just examples, no discussion. Like, a minimal example and one that goes all out, per post type. And possible, “traditional,” RSS alternatives.
Feel free to use or contribute to http://examples.tpxl.io - it sounds pretty similar to what you're taking about.
