The Allan R. Bevere blog, host to the "Methodist Blogs Weekly Roundup", has periodic polls. I found one interesting -- "Where do you prepare your sermons?"
The interesting part is that more pastors now prepare sermons at a cafe than at church, though most do at home. Perhaps cafes are getting more popular as a sermon preparation spot because many have Internet available (for research) as well as good lattes. The poll size is not large enough to warrant a high confidence level (+- 5%), but interesting nevertheless.
