some editors do their job and add most of the relevant sites that should be there on their own... then again, there is some editors that are just lazy and there for all the wrong reasons.
i was a dmoz editor for both commercial and hobby categories over the years and i can tell you that most submissions get a pass because 98% of them are spam.
of course you dont consider yourself site as spammy, but it may just be... if its clean, then sooner than later it will make it there
dont stress it too much
keep building your site
