I was thinking about different sites and how they organize their information. Some sites cite their sources at the end of the article which is great for users because it lessens possibility of rumor / myth. I also remember hearing about something similar to PR
but "TR" as in Trust Rank from google. I don't know if this is real, but could citing your sources help your rankings on individual articles?
Relates to the fact that google likes some outgoing links to related articles?
Just a thought
