The Fast Company article "It’s a Blog World After All" reports that uber-blogger, Microsoft’s Robert Scoble, describes himself as a "technical evangelist".

That’s a broad description, but it’s an excellent one. The article notes:

Corporate America is jumping onto the blogwagon for many of the same reasons all those journalists, brooding teenagers, and presidential campaigners are already on board. Unlike email and instant messaging, blogs let employees post comments that can be seen by many and mined for information at a later date, and internal blogs aren’t overwhelmed by spam. And unlike most corporate intranets, they’re a bottoms-up approach to communication.

It’s unlikely that Microsoft came up with Scoble’s term "technical evangelist". Therefore, when it comes to creating a job description for your company’s bloggers, let them make it up themselves.
