New editors often, in my experience, remark how difficult it is to tag (categorize) things on Wikipedia compared to Facebook and other modern sites. We have a useful tool, en:Wikipedia:HotCat, but there is no consensus from the community to enable it by default, as people are afraid of newbies messing up categories. The best solution I have, therefore, is to try to use some form of pending revisions with HotCat: enable it by default, but with pending revisions for new editors/anons.
