>My concern here is that I'm employed to concentrate on the SEO aspect of the business, and not being listed within ODP will hamper this process.
This is not a concern of the ODP, and it is sufficiently important that it CONTINUE being not a concern, that one can make it a concern only at the risk of loss of editorial privileges.
The ODP is not for SEO. Period. We don't help it, we have nothing whatsoever to do with it, and it is absolutely impossible that we hinder it. All we can do is decline to help increase a site's visibility. We can't get you banned at Google or any other search engine on earth.
One SERP perp, with whom I would probably agree on very few things on earth, told me something like "a marketing strategy that depends on the ODP doesn't deserve to be called a strategy at all." Well, with that I cannot argue.
