After the penguin update released, many SEO firms and SEO gurus are buzzing up about Directory listing. They keep on telling every SEO that directory listing is already dead. That directory listing is somewhat considered as spammy links where google might "quoted" penalized your site if it found out that your backlinks came from directory. However, there's no prof about it.

It's not dead. Quality directories will help you in SEO and PR rank. Google never gonna consider Yahoo directory, DMOZ and many quality directories as spam. Directories help visitors to reach businesses in a categorized format.
Quality directory submission sites still help in SEO. All directory submission site are not spam it depends on the sites..
