I haven't seen any other commentary on this subject, so I thought I'd draw your attention to the new feature for tagging words in the Vocabulary list. As well as helping you categorize your saved words, tags aid the community by making it easier for them to discover new words. When you (or anyone else) tags a word, at the bottom right of the sidebar menu, you will see other words tagged the same way. So the more tags the better!
