Regarding your edit, I don't think you understand how important technical evangelists are at places like Amazon, Microsoft, Sun, etc... They are essentially technical sales-people; they're the ones who say "Hey, this is what we're working on, and this is why it's important".

To be completely honest with you, your post seems like sour grapes.
