Favicon is the name of one of those things where you know what it is, you just don't know what it's called (like the thingie that holds the ends of your shoelaces together).

A favicon, or a web icon or urlicon, is the little icon that appears on the URL bar to the left. Google just updated theirs, and I've compiled the favicons for the Sugar sites here.

I get a certain delight when I see a favicon I haven't seen before because it just adds creativity and a great little detail to your website or blog!
