Preparation often seems to be used for questions about preparatory steps, but in which the 'preparation' has in fact nothing to do with the actual problem at hand (see the list of questions in the tag link).
There are a few questions in which its use is at least logical, such as the following:
- Can you use acrylic gesso for oil paint?
- What would happen if I machine laundered dry clean only fabric before making it into a garment?
- Efficient cutting and preparation of fabric for sewing clothing
But even here the tag doesn't add any information to the questions that is useful when writing answers.
The tag seems obsolete to me, as almost any step in a crafts project can be a preparatory step. It also won't be of help for users to find specific questions.
I think this is a good example of what the tagging help page describes as a 'meta-tag', a tag that is not descriptive of a question when used alone and means different things to different people.
On the other hand, the use of the surface preparation tag is a lot more consistent, and is without exception appropriately used on questions concerning the preparation of surfaces: its use is intuitive.
I would like to suggest removing preparation. What are your thoughts?
