Greg Veen gave a presentation on web fonts at the 2011 Web 2.0 Expo in San Francisco. He discussed the history of web typography from limited font support in early browsers to today's wide range of font formats and browser compatibility. Veen explained how web fonts can enhance user experience by allowing designers more control over typography. However, rendering quality depends on factors like font files, hinting, operating systems and browsers. Techniques like Flash of Unstyled Text and loading fonts with JavaScript aim to prevent delays as fonts load.
