DMOZ isn't what is was once paraded to be. Frankly, it's a joke of a project, but there's still SEO utility to be drawn from it.
I highly recommend applying to be an editor of your website's niche. I became the editor of my niche and there were about 600 websites in queue, many of them in queue for years. I'm confident that for most people, you'll become an editor faster than you website will roll down queue.
DMOZ is still a solid backlink. It's worth it because it shouldn't take you long to both submit your site and submit an editor application if you're so inclined. But it's not worth it to then check DMOZ every day and pine over admission to the DMOZ elite. Submit and forget.
