Abstract:

While you may not agree with everything Nielsen has to say, he's definitely provided a number of good tips on how to go about usability, and raised the awareness of user experience issues to a much broader audience - including those who sign the checques. The downside is that Nielsen's promoted 'usability' as being synonymous with 'user experience' to many people and we'll be clarifying the difference for years to come I fear.
