However, I had never logged in and updated a site such as Wikipedia or another "official" wiki until today.
The Minnesota Historical Society set up a wiki for the Susquecentenial titled: MN 150
On the site there are the top 150 topics answering this question:
"What person, place, thing, or event originating in Minnesota do you think has transformed our state, our country, or the world?"
I chose to edit the page on Cass Gilbert, archetect of the State Capitol. I added a link to my photos on Flickr of Statehood Day 2008, and included my photo of the capitol in the images.
I also added this information to the 23 Things on a Stick wiki.
I believe that the collaborative nature of wiki's is a perfect fit for education, from student created textbooks and study guides to authentic editing of wikis used in the "real world".
