Churches don't see it...

1452: Gutenberg invents the printing press, opening the way for the age of the mass printed book. Bibles become widely available and enter the home. The way is paved for the Reformation and the church is caught on the hop.

2011: facebook and Twitter have become common. Truth is reached through collaboration. And the era of truth being the monopoly of the expert, and broadcast from one to many by long talks is looking rather antiquated.  
Why do we train church leaders almost exclusively for a passing era?
