Every Few Years People Remember Websites Should Be Simple and Simplicity is Hard
UX Check is a Google Chrome browser extension that helps identify usability issues based on Jacob Nielsen’s1 website usability principles:
Visibility of system status: The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. Match between system and the real world: The system should speak the users’ language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.
