James Governor makes a small error in describing a putative Eclipse evangelist:
I can easily imagine a really excellent Eclipse RCP blog that was not written from a developer perspective, but that of an end user. So Ryan makes a great point but I would probably not be so binary. Authority and credibility comes in many different shapes and sizes. It increasingly comes from communities of interest, rather than "top down high church you shall obey" certifiers (Pace Michael Lewis and Stephen Johnson). High priest geeks are still high priests, and those are the folks we need to keep on their toes, regardless of the field of authority.
Eclipse's end users are developers, given the nature of Eclipse. IMHO, any non-developer evangelist for Eclipse would not be useful at the end user level - what information of use would they convey?
