Ask HN: Can Wikipedia's method of citing sources be improved? Has it been?

In short, i'd like to build a locally hosted (and maybe hosted alternative) fact aggregating system. My primary focus is to make sense of all the BS in the world, and live my life as informed as possible. I have poor memory, and i want to augment that with meaningful data. However, this project is not what i'm seeking information about, but specifically citing sources.

With that said, i dislike citing big articles as a "source" of information as the article often contains much more than the specific blurb. I want a better way to isolate the source, to know the fact.

Has anyone done this? In what ways do you think Wikipedia gets citing sources wrong? In what ways to they get it right?

Any comments appreciated :)
