I agree.. Trying to put the whole process into 3 short steps is difficult though..
I think because people define (and dont define) themselves as different things like "expert", "seller", "provider", or "qualified information source".. then its like what even is a "qualified information source" - i guess it could be a book? a website? a person?
we just need an all including, short word, for this type of person.. that people can identity properly as the person providing insight to the market researchers/product managers.
