Thanks to the hAtom format, the content of tumblogs using this theme can be extracted programatically directly from the XHTML. There are some limitations due to the way tumblr publishes audio and video content. I would have liked to have implemented the hAudio format for audio posts but this is not currently feasible.

- tramsformr
- buzzword
Also well worth trying out are these two addons for Mozilla Firefox that help you locate and extract microformats while you browse:
