Dmoz is very slow.

Hi,

DMoz is a human edited directory and Google always support the DMoz listing.
Not only every human edited directories are welcomed by Google. This is the reason why they take a long time in showing the post.

Thanks

Hey, I have submitted 2 of my sites for over 3 years now, but not even one is listed even now.

I personally think that many of the editorial people that decides to approve or decline sites also have their own websites listed there. This means there's less chance you'll get approved because your competition with them at the end of the day.
