The road to tech evangelism - IBM Watson

When you think about it, the tech world has a lot in common with old-time religion. There are impassioned camps -- think Android vs. iOS or Mac vs. Windows -- devoted to a particular software or hardware platform. And tech conferences that attract the faithful often embrace the fevered intensity of a tent revival. This isn't a bad thing, of course, as a little enthusiasm never hurt anybody. And it makes sense that major companies, including IBM, hire charismatic, persuasive individuals as evangelists to spread the word about their products and services.
