It's intended for schools and will be a pay-for service, but the core citation-creating tool is going to be available as a RubyGem. http://github.com/noted/scholar
As a student, I shouldn't have to know about complex citations rules while writing a paper. There are a few tools that take care of this, but they are either non-free (EasyBib), non-comprehensive (other online generators) or require that you use certain software (EndNote). To my knowledge there is no free, universal citation generator.
Great, thanks for the reply. I'm also working on something to compete with Easybib. But at the moment it definitely falls into the 'non-comprehensive' category that you mention.
