how things are categorized. As long as category intersections remain vaporware, there's no incentive to change. A technical fait accompli will bring about change.
Uhm, yeah.. except that intersection of atomic categories are not vaporware. We had proofs of concept for that and the interest was marginal.
In any case. If someone would really just shoved it into mw core and enabled it on all the wmf sites I'd be happy. I concur that it would make the job convincing useres of a less retarded categorization scheme a bit easier.
As far as Aeriks soapboxing from a few emails back goes: Let's not kid ourselves, tag based categorization is standard on commercial sites such as stockphotography libraries. We are not exactly inventing this...
I'll shut up now, and I really hope that this is the last time we're having this discussion... (but boy, you will get an earfull if it isn't ;-) )
