Quite often you'll see examples trying to bake the nature of "interface" into the interface name. Things such as "attachable" or "imageable" and the like, but what this is really trying to do is say "this model can adhere to the interface named attachable". Naming the interface something strangely related to the model that provides the interface such as "attachable" is IMHO trying to "name around" a problem which needs to be more clearly labelled or re-engineered.
In my opinion the idea of interface needs to be built into ruby and rails a bit better.
