I love podracer. It is a very simple tool for subscribing to podcasts. I just need to copy-and-past the RSS feed URLs into a text file, add podracer to my cron job, and all new podcast releases automatically show up on my download directory. Very cool. I just setup once and never have to touch it again, unless I want to change the subscription. I don’t have to remind myself to run a software or go to a web site to browse for new podcasts. I highly recommend Podracer.
