Here's a nice, brief blog post from Thom Schultz, the founder of Group Publishing with the "Kodak" analogy for the church, if you haven't encountered it before. Kodak was the only game in town for film, but has been wiped out by digital photography... a technology they invented!
In that analogy, I'd say that sticking with film for photography in the digital age corresponds to sticking with programs, property, professionals/pastors, and presentational worship in the post-Christendom age. But that's just me.
Or more succinctly, it's the mistake of thinking we are in the "large group weekly worship" business.
