It's a pretty big stretch to call your application a "Reddit for podcasts" when you only have an iOS application. The biggest part of Reddit is its web interface (and associated plugins), and your app doesn't attempt that.
The comparison with Reddit was mostly referring to the community curated feed of trending stories. I'm not sure what a Reddit plugin is (I'm not a regular Reddit user myself). But I agree with you that a big part of Reddit is the web interface and we are actually working on a web app to complement the mobile experience.
Why would you use something you don't use in your analogy?
