Mariano Amartino

Mariano has run the first WordCamp outside San Francisco almost 3 years ago, bringing Matt to Argentina… and he is helping people on at least 3 countries in Latinamerica to run their own WordCamps without even asking to be mentioned.

Mariano hizo el primer WordCamp fuera de San Francisco hace 3 años y trajo a Matt Mullenweg a Argentina (ya 2 veces) y ahora está ayudando a otros 3 países de la región a armar sus propios Wordcamps sin siquiera pedir ser mencionado y eso vale resaltarlo.

Dougal Campbell

Dougal was one of the original WordPress core developers, contributing features such as XML-RPC API support, mass re-enabling of plugins, Conditional GET support for feeds, and Post Custom Fields, which became the basis for countless plugin and theme features.

He has contributed several plugins to the WordPress ecosystem over the years, including Fancybox Gallery, Easy Gravatars, Theme Preview, and a filter for Talk Like a Pirate Day which has been subsequently adapted for numerous other systems including Drupal and Joomla.

Dougal has presented at WordCamp Birmingham for all three years it has been around, and was also selected as a presenter for the inaugural WordCamp Atlanta. Topics have included “The Future of WordPress”, which discussed upcoming features in WordPress 2.7, “Jumping Into WordPress Plugin Programming”, which will see an updated version at the October PHP Atlanta meeting, and “Pitfalls of a Popular Project”.

Clay Griffiths

Clay revolutionized WordPress theme development with the Headway Theme Framework. This was, and still is, the only theme framework with a full real-time wysiwyg visual editor.

Although this makes it easy for anyone to design their own WordPress theme, Clay has made Headway a very powerful tool for developers as well, with an extensive array of hooks and intelligent declaration of CSS selectors.

Version 2.0 of Headway brings a huge array of enhancements and optimizations, all coded by this brilliant up and coming developer.

Headway and Clay are certainly ones to watch in the WP community.
