'Folksonomy' Carries Classifieds Beyond SWF and 'For Sale': Today's New York Times has an article discussing folksonomy and specifically tools such as del.icio.us.... I tag sites that I'm going to share during the presentation with a common tag, then load them up in Firefox using their live bookmark feature.

Since the files ended in a .mp3, del.icio.us added them to a unique RSS feed: http://del.icio.us/rss/timlauer/system:media:audio+educast If others also used the tag, educast to tag educational related podcasts, then I could also subscribe to those postings by using this URL: http://del.icio.us/rss/tag/system:filetype:mp3+educast This can get pretty powerful when other folks are tagging items. For example if Tim Wilson, or Steve Burt, or Meredith Melragon uses the educast tag to identify podcasts that they find of interest, these will pop up in iTunes or in my RSS reader, Netnewswire.
