Directory entries are often mentioned as another way to promote young sites in the Google index. There are great, topical directories that add value to the Internet. But there are not many of them in proportion to those of lower quality. If you decide to submit your site to a directory, make sure it's on topic, moderated, and well structured. Mass submissions, which are sometimes offered as a quick work-around SEO method, are mostly useless and not likely to serve your purposes.
Yes Directory Submission is Good for young websites .
Some Webmasters Found its good to build links from Directories while other reported it as bad techniques .
I found its Good technique and one should build links from directories , again quality and relevancy the two main seo factors lies here too .
As 4tuffs suggested is good Idea .

Depends on a directory. Better focus on the few high quality directories like Dmoz, Yahoo directory, etc. and try to get there. Most of other directories are not welcomed by Google warmly. And to remove websites from them later after you are punished by Google will be much harder then making a right decision now and not posting it at all.
