DrupalCamp Manila: Mastering Usability Principles
Jakob’s Law: Users spend most of their time on other sites. Don't reinvent standard patterns (like navigation or search icons) just to be clever; familiarity breeds comfort and ensures intuitive use.
The "Admin" Persona: Treating content editors as first-class users. A Drupal site fails if the backend is a confusing mess of unstructured fields; configuring the editorial interface (WYSIWYG, help text) is as critical as the frontend design.
Performance is UX: A slow site is a broken site. Understanding that "Perceived Performance"—using techniques like skeleton screens and lazy loading—impacts user retention/bounce rates far more than visual flair.
Heuristic Evaluation: Moving beyond "it looks good" to structured auditing. Using Nielsen’s 10 Heuristics (like "Visibility of system status" and "Error prevention") to objectively measure and improve interface quality.
