I don't think I've announced here, but in support of the podcastindex.org project, I cooked up a lightweight, responsive webapp which you can run from:
It lets you browse the newest podcasts, zoom in to one single podcaster, search for podcasts by keywords, filter by language or categories. It can also sync across your devices.
It's mostly developed to provide feedback to podcastindex's technical design. But feel free to request features.
