Difference Between A Blogger and A Citizen Journalist !

Many of writers online use the two words blogger and Citizen Journalists interchangeably but as the online sphere develops and the issue is critically analyzed a dichotomy is starting to emerge.So is a Citizen Journalist and a blogger one and the same thing? what differentiates or defines the two? This question is pondered upon by Susan Cormier of the National Association of Citizen Journalist(USA)  in the following YouTube Video:





In an attempt at defining Citizen Journalism Wikipedia offers the following definition /opinion:

Citizen journalism (also known as "public", "participatory", "democratic",^[1] "guerrilla"^[2] or "street journalism"^[3]) is the concept of members of the public "playing an active role in the process of collecting, reporting, analyzing and disseminating news and information," according to the seminal 2003 report We Media: How Audiences are Shaping the Future of News and Information.^[4] Authors Bowman and Willis say: "The intent of this participation is to provide independent, reliable, accurate, wide-ranging and relevant information that a democracy requires."
Citizen journalism should not be confused with community journalism or civic journalism, which are practiced by professional journalists, or collaborative journalism, which is practiced by professional and non-professional journalists working together. Citizen journalism is a specific form of citizen media as well as user generated content.

I believe differentiating the two offers fine lines for critique and Divergent viewpoints,question is which preceded the other? are the two terms mutually exclusive ?is there a point where the two converge? Well the purpose of this post is not to theories the application or definition of the two terms but to highlight the emerging trend of differentiating the two and to solicit diverse opinions on the issue-your take?
