It's not hard to find your post at R-Z from 2004 where you wondered why your site was removed from the public view, at which point you were told that it was moved to a different category because the content had changed. I was naturally curious after that, so I checked to see if it's been added since that post.

If anyone wants to be in the directory specifically to get traffic to their site, then, as you've already pointed out, they'll be very surprised when the numbers don't add up. For webmasters, there is no incentive because Dmoz isn't designed to meet webmaster needs. It's also not about people choosing to want to be in Dmoz's directory, because editors can add sites with or without anyone's permission. As long as our visitors find what they're looking for, then that's all that matters. And, to be honest, I tell people not to worry about Dmoz and just submit and forget, because Dmoz will not meet their needs as webmasters. Now, Yahoo, on the other hand, might offer them what they want as far as being obligated to them, because Yahoo offers a service to webmasters.

And, just FYI, this is all my opinion. I don't speak for the ODP or its editing community, and another editor might chim in with a completely different opinion of the situation. But, you can tell where webmasters stand in Dmoz's eyes when webmasters complain about Dmoz to no avail.
