OPML PopUp to ease Podcast Aggregation

Published in: JavaScript 

URL: http://www.productivity501.com/2006/11/free_academic_p.html

This is a website specific script... pops up the source of an OPML file with 145+ podcasts. http://www.productivity501.com/2006/11/freeacademicp.html

Note: The 'bookmarklet' format is included as a comment at the bottom... (write in a webpage an anchor element with the escaped javascript format in the href attribute).

  4. * Either way, you need to copy and save the results as a file with an .opml extension
  5. * You can then add it to your Aggregator of choice:
