The abbr element

«So much of my time as a web developer has been spent hiding things away from users so they can later reveal them and so much of that time I should have just left things as they were. If you are looking for User Experience advice from me, it is this: stop hiding things behind tabs and in popups or inside attributes. Stop making users go looking for things!»
