del.icio.us has a new feature that Joshua, its creator reported here on his del.icio.us blog. Media files (video, audio, images, and document) are now tagged and can be rss or used in podcasting.

The tag “system:media:audio” includes

* *.mp3 tagged as “system:filetype:mp3″
* *.wav tagged as “system:filetype:wav”
The tag “system:media:document” includes:

* *.pdf as “system:filetype:pdf”
* *.doc as “system:filetype:doc”

Relevance
del.icio.us is evolving beyond urls into the tagging of digital artefacts (documents, pictures, and music). It is moving from a bookmarking tool to keep track of cool urls (which we used to use our internet browser for), to a system that used tagging to better organise and share information personally relevant.
