Manifesto

Shopping

• get your products to web fast
• get customers to your products easily
• get your customers money fast (they actually want it too)

Usability

• Less is more
• Content is the king
• Dont make me think

Application development

• Standards are good
• Simplest possible solutions
• PHP is a templating language
• DRY
• MVC on server side and client side
• Convention over configuration
