ChurchTechArts is the most widely-read and trusted website for production technology in the house of worship category. No-nonsense equipment reviews, production tips and philosophy of ministry discussions are all part of the three weekly posts. Written by Mike Sessler.
I just dropped by Garr Reynold's Presentation Zen site a little bit ago. Check out this article on a book he recommends. There are some really good ideas for creating more effective slides for your PowerPoint or MediaShout presentations. And read the rest of the site, too. I always learn something or am inspired when I do.
