Jeff Sandquists's bird/elephant analogy throws things off a bit (um, gross Jeff), but over on his blog, he shares a job description for an open Technical Evangelist (TE or phonetically, Tee Eee...whee!) role reporting to Jeff himself. TE roles have always been a little hard to describe. It's easier for us in staffing to describe in terms of what we want the person to be (technical with great marketing skills) versus what we want them to do (with those great technical and marketing skills, you can do it all, right?). So it's best for you to hear ot from the folks that actually do it, right? Check out Jeff's blog.
