Parameters of survey pool – people writing “jblogs” who don’t identify as journalists

I’ve NOT sent the invitation to people keeping blogs on MSM websites who are clearly framed NOT as journalists but as civilians doing interesting things keeping a blog.  If it is ambiguous whether or not the person is a journalist, I am sending the survey.  One individual has already written back to ask if s/he should complete the survey because s/he does not self-identify as a journalist.
