Transparency is the new objectivity

After reading "Transparency is the new objectivity," different questions popped into my head. In my Journalism Ethics class last semester, we talked often about transparency with citizen journalists. The biggest issue was being able to identify the reporter/writer and how to contact them. This article talked about many ways to be transparent, mostly about writers disclosing their own biases. But after looking over all of these suggestions, I wondered, are there levels of transparency? Do larger stories need more information to prove objectivity? Does that include name, title, contact, resources and links? Could some blogs just out right say their bias and that be the end of it? How much is necessary, sufficient or superfluous?
