Getting in DMOZ is not hard at all, you just have to submit to a proper directory, study their guidelines word to word and have a useful website. I got one of my new websites listed within a week in a PR5 category.
Yep thats true...i got my 2 sites listed withing 2-3 days.... But it actually depends on the editor of your category, if he is active then your site will be listed soon, if your site is worth listing!
