Podcast help

So I'm getting sick of iTunes.
I've been using it for over a decade since version 1.0 and quite frankly I don't even own any Apple products anymore. Here's an issue though. I don't know how to find podcasts if they aren't in iTunes.

I'm switching over to Media Go because it has more useful features than iTunes and a hell of a lot less bloat. Media Go has a Podcast Search Engine built into it, but it doesn't find everything. For example some of the recommendations in the Favorite Podcast Article aren't there. The bright side though is that there is a manual URL entry field so I can manage them like an RSS reader.

So how can I find Podcast URLs when they aren't readily available from the built-in search engine?
