As soon as website visitors use the term user friendly, they actually are talking about what web designers refer to as usability. Usability is a hard thing to characterize because every one of us possess our own opinions on the subject of what it really is to be user friendly. Like art, you merely identify it when you observe it. As many users as possible should find the web site as easy to operate as possible. For a web site that attracts thousands, even millions of website visitors each month, usability is a important ingredient to success.
