Can you give me advice about our Podcast?

I have recently been assigned to work on the website portion of the Media Ministry at my church. As part of our website we produce a weekly podcast. Right now each episode consists of the sermon from the Sunday morning service. I would like some unbiased opinions about how we can make our podcast and website better so that we can do our part in spreading the gospel. We would like comments and suggestions our sound quality and site design. All comments are welcome, but we would especailly like to hear from those who have experience producing church websites and podcasts.
