Sooner or later you'll have to create Your Personal News Agency. A reader or any aggregator is just the INPUT part of the job but how do you process and make available the generated knowledge, the OUTPUT? In a wiki or a blog post? None of them are semantic so inapropriate for storing knowledge.

Future Readers must focus on the output part of the process otherwise there will be so much input without proper output that everything will look like noise.

Signal vs. Noise is in fact your I/O rate.
