How do you imagine sites that are ad free would appear? What's their business model? I don't think that's a given, especially since most users won't pay (see the rise of freemium style apps vs paid ones in the app store).
It takes time (that's money) to create quality content that anybody would love reading. Heck, even content that's crappy takes time to create.
I'm also fine with ads in podcasts since the creators will sometimes at least use the product and it's implemented in a way that's largely expected, e.g. (plug in the beginning, plug in the middle, maybe a plug in the end...)
So is that site still up? If not, why did you stop? Too much effort to keep it running?
