Why are those most in need of constructive advice the least likely to listen to it? [Rhetorical]
This phenomenon is not confined to DMOZ management, of course (although that is a great place to start). The same principle applies to any situation where someone's high opinion of themselves exceeds their capabilities.
The Open Directory Project has recently been granted the dubious benefit of a third group of volunteer administrators (NB that page is seriously outdated, by many years!), the first and second groups having mostly mysteriously disappeared.
Due to self-imposed (and self-protective) restrictions, I am unaware of the details of these new promotions, and of the reactions of the volunteer community, but I can guess. The appointments are likely to be as inexplicable and idiosyncratic as previously, with scant regard for the needs and concerns of those volunteers who do the actual work.
This is particularly unfortunate for those landed with the role, as they almost certainly believe they can effect the necessary changes.
Sadly, this is patently impossible, but we do wish them well.
It is needed.
