we're thinking of unifying datatypes and cardtypes into cardegories. (This was in fact done.) this means cardegories will be addressing all the needs presented by those.

addressed / organized by cardegory:

• primary content interpretation & validation
• categorization
• user customizations
  
  • tag cloud grouping
  • formatting
  • default layout??
• developer customizations
  
  • query tabs
  • extensions
• microstructure?
• defaults
  
  • permissioning
  • content
  • related cards
