It’s worth remembering that the entire point of a wiki is that it’s quick and easy to make a change (the name means “quick” in Hawaiian). Being quick and easy to change was the defining quality of Wikipedia and its advantage over more rigid traditional encyclopaedias. These days editing Wikipedia seems like you have to fight bureaucracy and rules lawyering, and doesn’t seem very wiki-like at all.
