My reading queue is way to long and I have reads tucked away everywhere: Instapaper, Things 3, a reading.txt file.
Cleaning this up giving the number of pieces is going to be a complete mess.
But the only alternative is to nuke the collection, and then, probably, start anew…
The only long term solution is to change the way I do things and make new rules for the amassment of articles and content online. In this regard I have thought about starting to print the best pieces and articles. I bought a printer and intend to use it to this end.
I also found this article on printing a book with articles: Instapaper (analogue edition)
