On directory submission

I wonder how many people actually go look up sites in a website directory? I thought people either still used Google or looked up stuff on Digg or Technorati or Facebook or other social media sites? Yet there are a lot of website directories, and people putting up web sites pay people for directory submission, so their sites can be listed in the directories. That is one way for Google to find your new websites, and get some link juice. The best directories are very helpful. But DMOZ is a joke and nobody understands why Google gives it any credibility anymore, since it's totally dysfunctional in terms of evaluating new sites and adding them. It doesn't. It's not worth the time to make a submission.
