From Ed Brill's site, Chris Blatnick is featured on The Employee Factor site as an "Employee Evangelist."

What is an Employee Evangelist?

An employee evangelist is someone who believes so much in the company they work for and the products they sell that they passionately commit themselves to them. The evangelist becomes both an internal advocate and external sales force with the sole purpose of promoting the product or service that they love.

How does Chris view evangelism?

I believe evangelists also have an innate desire to help other people.  That desire, coupled with their sincere belief in the product or service they love, helps drive them to become an evangelist in the first place.  They also are generally very motivated people.  Being an evangelist is not just a 9 to 5 job.  Rather, that person puts in the extra time and effort that it takes to preach the message to others.

Many of you know Chris or have seen him speak at many conferences. You can sense his enthusiasm for the Lotus product offerings and his passion for creating better applications. His interview will provide you with some great insight, ideas, and appreciation for the benefits of evangelism.
