How much of that information is novel or new?
I bet very little.
The content system that only records novel informationImagine you have a web application with an input box and a "submit" button.
You enter information into the input box and click "submit".
Then the application runs a Google search for what you entered and posts it only if it finds exactly zero results.
Your network gets:
Lots of original information.
Highest ranked Google results for every page in your content network.
Great advertisement property.
Maybe this should be done only for the title of the post. It needs some testing.
