Our impression is that Google updates the ODP about once a month...but some months, the update fails for some reason.
(What reason? We don't know; not our problem. Will it be fixed? It always has been before. By whom? Either ODP or Google techs, not by editors. Is there anything ODP editors can do about it? No. Do the appropriate techs know? They usually do. Is there any way to notify anyone? No.)
All our regular licensees are out of date. For that matter, our own public pages are out of date -- only the editors are sorta-guaranteed to see the latest: absolutely guaranteed only if they actually edit the category.
Is this a problem? No, it's the nature of directories that there's a long lag time. So directories "favor large, stable sites." For instance, we don't list single-item-for-sale or single-product-intro-promo websites -- because by the time our licensees (whoever they are, whenever that is) update, those websites are likely to be gone. And we don't list individual breaking-news stories (although we do list some archived stories). And so on.
We take the long view. Do you want short view? check out eBay, the New York Times, ABC, MLS, and the like.
