ReadPapers, in a nutshell, is a bookmarking web service. Given that we have many of those around, what's so special about this one? Its focus on PDFs.
It is built and maintained by Tim Marinin and hosted by Digital Ocean in FRA1 datacenter.
ReadPapers is not built by some faceless corporation, and I am open to suggestions on what feature to implement next. Don't hesitate to email me at email@example.com.
