It has been a while since I looked at the FamilySearch Wiki.
The site now has more than 40,000 entries. Like any Wiki, especially at the beginning stages, there is a wide variety of quality, and especially of completeness. However, it is already a very helpful place to go to find out about researching in a new locality.
I went to the North Carolina Barn Raising (actually started in May 2009) and signed up for the North Carolina Archives and Libraries and North Carolina Bibliography pages, and I have made some edits. As with any wiki, editing is quick and easy, and can be done in a format-based view or in a wiki code view.
