Scoble has this great post summarizing a meeting he had with Brian Bailey, Internet technology manager for Dallas' Fellowship Church. Scoble summarized the ten evangelizm and IT lessons that have contributed to the church's success:

One: make it easy for everyone to learn about you -- on their terms.
Two: make it easy to experience your product's special attributes.
Three: to get word-of-mouth advertising you need to be remarkable.
Four: use IT to efficiently get close to your customers and take care of their needs.
Five: if you want to be better, make sure you're better from the first minutes of someone's experience.
Six: if you want to be seen as bleeding edge, invest to be bleeding edge and do so throughout your company.
Seven: extend the usefulness of your plant.
Eight: design your systems so they never go down and can expand for future growth.
Nine: don't be religious about technology, choose what gets the job done best for the least amount of money and staff time.
Ten: when you become successful, bottle up what got you there and sell it to others.

The lessons are great, and Scoble elaborates on each. Read the post, which I think is Scoble's best ever.
