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
- microstructure?
- defaults
- permissioning
- content
- related cards
