Just found out that del.icio.us automatically tags certain file extensions with tags like system:media:audio and generates RSS feeds with enclosures (like http://del.icio.us/rss/tag/system:media:audio).
Combined with an RSS-aware media player like DTV, this makes for a cheap way to create your own TV channel.
One of my current projects requires similar technology – this will be useful for testing, at least.
Yeah its pretty sweet to combine tags with filetypes
I like popular mashups and funny videos…
