Giving feedback when users are hovering over something that is clickable or interactable (is that even a word?) is generally considered good design. For text, you have many ways of indicating a hover - ways such as underlines, color changes, etc. For blocky, box-like things like images or divs, one of the most common things you can do is show an outline or a border around the element when you hover.
This is a companion discussion topic for the original entry at http://www.kirupa.com/html5/display_an_outline_instead_of_a_border_hover.htm
