That’s what surprised me the most too. MAYA Design was behind the rebranding and site many years ago, why not use an agency now, when online presence is more important than ever?
To build a site like this, you need:
Creative Director: overall design
Interaction Designer: personas, wireframes, prototypes
Information Architect: organization, navigation, taxonomies
Usability Engineer: user testing
Visual Designer: visual concepts & assets
Editor/Copywriter: writing
Photographer: headshots, reporting
UI developer: code front end, HTML, CSS
Backend developer: coding all else, IT
QA: testing
Webmaster: daily content management
Was this student responsible for all of these roles?
Since INNOVATION is apparently the crown-jewel of IDSA according to the most recent survey, it would think to grow that staff and place IDSA.ORG under their responsibility. Treat it like the online magazine it is.
