If I were to describe Font Awesome in a word, I think it would be...awesome.  The icon font library is massively helpful in using quality vector glyphs instead of  separate images.  I tend to use a lot of icons within links, as they help users to more quickly visually identify navigation.  One side effect of using icons within links is that the icons themselves now use the text-decoration of the link.  I really don't want icons underlined like the link -- it looks tacky.  Here's how I remove them!
