Tips: New system tags in del.icio.us for fetching filetypes and podcast

From the del.icio.us blog, Joshua mentioned he has done a new feature called system tags which add support for finding medias:
There are couple of extra tags you can use now:

The tag "system:media:audio" includes

• *.mp3 tagged as "system:filetype:mp3"
• *.wav tagged as "system:filetype:wav"

The tag "system:media:video" includes

• *.mpg tagged as "system:filetype:mpg"
• *.mpeg tagged as "system:filetype:mpeg"
• *.avi tagged as "system:filetype:avi"
• *.wmv tagged as "system:filetype:wmv"
• *.mov tagged as "system:filetype:mov"

The tag "system:media:image" includes:

• *.jpg as "system:filetype:jpg"
• *.jpeg as "system:filetype:jpeg"
• *.gif as "system:filetype:gif"
• *.png as "system:filetype:png"

The tag "system:media:document" includes:

• *.pdf as "system:filetype:pdf"
• *.doc as "system:filetype:doc"

You can also getting RSS feed for podcast etc if you go to http://del.icio.us/rss/tag/system:media:audio for example. Pretty useful feature!
