To start with, you don't know that an editor has visited your site. There are several automated processes that may leave a hit in your weblog from somewhere in dmoz, but that doesn't mean an editor has actually visited your site.
Secondly, editors are volunteers that are able to choose what they want to do. I'm currently in the middle of clearing a backlog of over a thousand sites from one area of the directory and I'm finding lots of misplaced entries. If I come across a site that's difficult to classify, or wildly misplaced, I leave it alone and head off for easier work. I'll come back and do the difficult ones one day, but right now my time would be better spent listing good quality sites that have been properly submitted.
