A new section on the main page has been suggested to encourage editing of more topics. This box would contain broad topics that may persuade a reader to become an editor. Some argue that this will not serve the purpose that it was intended to serve.
HotCat has been suggested to be turned on for all users to aid in the process of categorizing Wikipedia. Arguments against the proposal include the lack of double check feature and no way for administrators to remove it from someone that abuses that feature.
