References and a reference engine would be a tremendous help, both for readability, and for writing. I would like to suggest a project: wikicite which would list all available books and create a simple tag mechanism for citing them.
Thus something like {{wikicite:Wealth of Nations}} would expand out to a canonical Smith, Adam etc.
Getting journal articles would be next, and harder, but could be worked out over time. This would make entering sources and bibliography easy, standardised, and current. It would also keep the burden of generating citation lists down, and would be a generally useful resource everywhere.
