For years I've benefitted from the wealth of information on Wikipedia. However, sometimes I'm looking for info on a topic and the Wikipedia page just doesn't have it. In the past, I sighed and returned to Google. Now I click "edit" and add what I know. This leads to an increasingly eclectic smattering of contributions.
I've researched citation use in Wikipedia, so you can be sure I'm adding citations as well as I can, though that tricky reference-formatting forces me to preview pages far more times than I'd like.
