Blogging Journalists... do they sacrifice their objectivity as a blogger?

In the course of interviewing four media experts for my mid-term project we got into journalists as bloggers as they each discussed their definition of a journalist. One of "experts" sent me this article that appears in today's Editor and publisher... the article "The End of 'Objectivity in New Journalism: A Good Thing?"... raises issues germane to our discussion on the use of technology in the future of journalism... should standards change based on the medium a journalist uses?
