HuffDuffer: like the Tumblr of podcasting
Huffduffer will stitch audio files into a podcast for you, and put them into an RSS feed automatically. You can add your own styff, or throw together some of the great "inspiration" that's already on Huffduffer. They've linked some of the best free content on the web, like TED talks and This American Life. To make things even easier, there's a browser bookmarklet you can save, to easily Huffduff any interesting audio you run across. I'm already thinking of Huffduffer as the Tumblr of podcasting: good concept, great ease of use, definitely worth checking out.
