y, I'm not sure websites for podcasts are a problem.
If you host with castos.com or transistor.fm you get a mini site where your podcasts live on their domains. So I'm not sure having a website is an issue for most podcasts.
I think a podcast website offering would probably be easier coming from their podcast hosting company that way the website and podcasts are with the same company.
So it doesn't seem like a natural fit for the company doing the editing.
