When introducing non-Wikipedians to the concept of Wikipedia, I've found many people want to know: *how does an article develop?*
I just composed an overview of the development of a GA article I worked on with several others over several years:
http://outreach.wikimedia.org/wiki/Evolution_of_an_article_(Celilo_Falls)
And also, started a page on the Outreach wiki to link to such stories. I linked to several time lapse YouTube videos I've seen that do more or less the same.

Does anybody else have an article they'd like to explore in this way? Or feedback on the Celilo Falls overview?
