Why is there still a web archive for the newsgroup?

I wonder what effect this has on PageRank. I have been told that 
Google can identify a site as an originator of content some 
times, and could reduce the rank of another site based on that, 
something like that. Then again, all SEO is basically nonsense, 
due to nobody truly understanding Google and the inevitable 
nature of Google growing too complex for anyone to be able to 
take any action that isn't just "show good content, format well."
