Just a note based on what you wrote - we don't use webpage design as a criterion for acceptance of sites. If a site contains useful information, which, as you say, isn't illegal, then eventually it will get listed.
I can understand your frustration, though - because of the shortage of editors, in some areas of the directory we have sites which have been around for a lot longer than yours - it's not a situation any of us are proud of, but we are all volunteers and have limited time - we're doing what we can with the time we have.
Have you considered helping out and becoming an editor yourself? :/images/dmoz/purplegrin.gif
