For a variety of reasons, I'm not able to podcast every sermon, but every worship service is videotaped and uploaded to YouTube (and put on a few DVDs for our homebound members). The sermon starts about 30 minutes into the service. The only downside to the video is that audio may not be as clear as in the podcasts. The upside: You get to watch the children's lesson, which is always a little random and humorous. Also, I've recently begun preaching without notes (i.e. without looking at a manuscript while talking), which I think makes the sermons better. See for yourself!
Here's a recent sermon from August 10, 2014, when I preached on Evolution, in a sermon series on Reconciling God, Science, & Nature. It was my first sermon preached entirely without notes. We start reading the scripture and preaching around the 40-minute mark.
