That reminds me that I have only ever created one new Wikipedia page myself, and that is on Michael Goulder. I wanted to do this in part to test the claims about the unreliability of Wikipedia. Would people come in and deface what I outlined on Michael Goulder? On the contrary. There is simply a welcome invitation, to me or someone else, to improve the article:
This article or section needs sources or references that appear in reliable, third-party publications. Alone, primary sources and sources affiliated with the subject of this article are not sufficient for an accurate encyclopedia article. Please include more appropriate citations from reliable sources.This is something that seldom gets mentioned by those who prefer not to engage critically with Wikipedia, that it actually encourages authors and editors to provide proper citations for the claims that are being made, a very useful encouragement to students who are learning about academic writing.
The only other one I've contributed to has been the entry on E. P. Sanders, where I made one or two minor edits to improve accuracy, and added a couple of references. That was over a year ago, and they have not been changed or edited away in the interim.
In this category, my feeling tends to be more sympathetic to those who wish to engage critically with Wikipedia than with those who wish to turn their backs on it, but perhaps that will change in time as the site continues to grow.
