Founder of the popular WordPress voting site, WPVote and big contributor to the WP community with great tutorials, and resources. Ben is a WordPress developer, and has had a hand in creating some really awesome themes from ProThemeDesign.
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.

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.
