The more generic the system the more generic – and therefore less usable and more bland – the content will be.
For example, text that needs to be used across several websites intended for different purposes and different people will most likely need to be more generic to serve all those needs. Since it’s not customized to any one context or type of reader, it loses it’s voice and specificity. (Yuck)
I need Matt to come up with a name for this.
