The only way to really build up some links quickly is to submit to paid directories and buy a few links. Otherwise you just have to be patient, the links will come if you keep submitting. good luck
It's the free submissions that don't get reviewed in an orderly fashion. We opened Yutter for pre-registration last weekend and we got a few thousand submissions in about 30 hours. We've only gotten through about half of them. But we've gotten through every paid submission within 24 hours. We stopped taking free submissions because it's just not worth the time and energy you need to keep a respectable directory with all the junk that usually comes with free submissions. So I would say find some cheap directories and pay a few bucks, it'll be worth it. David
