I've seen some brilliant people here and I'm pissed off because I need to pay big money for research papers. After reading https://news.ycombinator.com/item?id=11279903 I don't see why can't we create our own system.
Some points:
1.) people can upload different versions of the document (you would want to change if someone tells you that you have a typo)
2.) people can comment on documents
3.) upvote-downvote system
4.) free, open source, no ads
I can create a simple codebase for this and I will need help if things get bigger.
What do you think? Your honest opinion is most welcome!
