I could not get my site added in DMOZ even after many tries. Unless your website is really extra ordinary the chance of rejection is pretty high.

Back when DaniWeb was my personal site about my dogs, we were listed in DMOZ. Once DaniWeb turned tech, it took me nearly a year to get DMOZ to update their listing.

I finally started a thread at Resource-Zone (a forum run by DMOZ moderators) and Bob was able to help me. (Bob being a DMOZ mod whom I had already known as the former owner of a popular visual basic forum.) So I'm not sure if I was just one of the very lucky ones who ran into an Internet acquaintance who just so happened to have been in a position to help me.

Well, I'm going to submit my site today and hopefully I'll have some luck. I will let you know guys if ther reject me...lol.

Its really difficult to get listed on DMOZ, more over editors are bit harsh. You will never come to know as why your site was rejected or its under process. Ask them on their forums and you will get a harsh reply for sure.

Yes it will be very helpful to get listed their as many web directories just full their databases from this directories including google. But you will not find any one searching personally in that directory.
