Maybe not so technical but as a curious person i feel i collect so many articles in instapaper but never take the time to reread them.

I do read though, mostly offline. Books, newspapers and articles. My focus is better offline.

Combining data mining and my offline focus, it would be great if you could make a tool that categorizes my instapaper articles and converts it to theme numbers (big data, health care, artificial intelligence, food, etc) that can be downloaded in pdf.

Would be so cool! Thanks for asking the question.

Or! Sent periodically as a custom magazine when the theme has received enough articles / reach a volume threshold to justify the print and sending.
