The question now is:
How long will they take to "fix" the article?
At least the online version can be fixed, but a print copy needs an errata
in a subsequent edition.
Will they pay attention to letters to the editor about it?
Will they fix it at all, or even acknowledge the error?
I suggest that a number of us write in about the goof, preferably from
academic e-mail addresses and include full titles. This sort of thing
should be fixed if possible. A journal should at least use correct
terminology, even if the articles are not as good as they used to be.
