I selected the New York Giants page because unlike other sports teams pages they did not include nicknames. I took the Giants page from wikipedia and added in their most popular nickname to the logo and uniform section, because their blue uniforms are how they gained their nick name "Big Blue". It was posted 11/29 at 12:00 and still has not been removed.
It is clearly very easy to temporarily change a wikipedia page as seen by the multiple changes made by the students in class. However, many are eventually removed in a few days showing that there are people who check. It still raises questions about who reads and selects what stays and goes, and also why certian things are removed. Other alterations are true, but for some reason are taken away.
I will repost in a few days about whether or not my addition of the Giants most famous nick name stays up on the page or is taken down.
