I built this for fun and I can say that it was fun to build! It's an experiment too. But prior to building it, it was something I could see myself using.

To entice users, I have thought about adding features that users find directly useful to their work (e.g. the ability to take notes on papers within the site and export them), or the ability to export saved articles as bibtex... but I'm still thinking this through. Open to ideas.
