Paper writing is hard. Adding more material - even supplementary material just slows down the work of good people.

On the other hand, I do feel like there should be websites where papers can be annotated by readers, who can provide missing details etc. Though this does require a lot more papers to be open access.

On the other hand almost all papers have a short introductory section where they present basic concepts in a concise way. I find them great for learning and reinforcing concepts. They should be collected together in a wiki. We would have dozens of variations for each concept and great coverage.

Primary problem is interest, really. No one's going to annotate "The Last Ditch Journal Of Applied Theorem"'s non-headliner papers.

Basically something like rapgenius but for papers?
