I'm wondering whether the site is listed in the Yahoo Directory, and, if so, whether the "noydir" attribute is still necessary to keep the Yahoo Directory title and descriptions out of the Yahoo serps.
I've just continued to use NOYDIR as a matter of course, along with NOODP, but I'm not sure what may have changed in recent years.
See discussion here from 2007...
