I saw that, but I'm not sure it will fit my needs. More than anything else, I want to be able to use the "play/pause" key on my keyboard to pause the podcast. I also really like the idea of the voice booster and I'm guessing that the web site won't get that (being 'basic' and all).
Don't expect the web app to become any serious Mac app competitor anytime soon. Based on Instapaper's website, Marco dislikes working on them. It will keep basic functionality but his main focus will be on iOS for the foreseeable future.
