Creator of Caster Club and Podpage
I know they're not the best, but I used this because they're easy and I already have them around. I need to upgrade to something better at some point, but for the time being, they do the trick.
I read Podnews every day. There isn't another newsletter that captures the industry as a whole in such a quick, simple format.
Podpage makes it easy to spin up a website in 5 minutes. It's not as customizable as wordpress, but it's easier and requires a lot less time and effort.
