It is not surprising to me at all that the survey clearly shows "artist" being preferred to "craftsman/craftsperson".
So there is definitely still this thing between "art" and "craft".
It seems to me the term "craft artist" is an attempt to avoid the destinction between art and craft.
Who uses this term? No-one I know refers to himself/herself as a "craft artist". (But who do I know anyway?)
Could it be that some crafts people feel that adding the word "artist" adds a bit more status ?
Could it be a genuine attempt by people whose work is a mixture of art and craft ?
"Crafter" is just a stupid word, in my humble opinion.
I respect craftmanship and I appreciate art, but I do not respect the rubbish that is often presented as "art".
