I've tried submitting my niche authority site a few times under different categories spanning a few years' time. Each time I never hear back. To me that's the problem. Hell, I'd be happy if I got an e-mail 6 months after I submitted saying anything (good or bad). But if I wait a year, of course I'm going to resubmit. It's frustrating and it's too bad DMOZ counts for anything in Google's eyes. It's a has-been and clearly there's a lot of issues that need to be resolved if/before it can be "good" again. My view on DMOZ is not high anymore... I've submitted to be an editor in a few different categories where I have knowledge but I was denied. I tried to help. So what am I to do? Give up.... yes, I pretty much have.
