I think that the key to making a directory stand out would be to totally rework the structure. Not just a slight change, but entirely new.
The ODP revolutionized the directory world. So much, in fact, that not only did everyone after them follow their lead, but even Yahoo changed their ontology to be closer to ODP's.
That structure was fine for 10 years ago, but so much has changed. Just a small example, the Computers category was grand for its time, but computers are no longer the only way to get the get the internet. And now that cell phones contain computers, what needs to be done?
Just my 5 cents worth...
