del.icio.us Social Bookmarking - Creating a reusable copy of a 'tagged' RSS file
As mentioned in the intro, the following code will create a local copy of the latest RSS feed for any particular tag on del.icio.us social bookmarking. The general idea (at least what I'm using for) is to take a bit of the load off the del.icio.us servers, make them available from a site that is focused more towards this particular tags content, and as a result be enabled to embrace-and-extend from there in any particular direction you feel appropriate.
