Yahoo directory offers paid and free listings for websites. The processing time for submissions is much faster than Dmoz in most categories.

The categories are uncluttered and the organising is excellent. But some feel that it carries less weight than the Dmoz though. Dont expect much traffic, but it will help your yahoo rankings.

Dmoz is one of the top human edited directories in the web. Google gives this directory authority status and therefore just about every website listed there get some boost in their credibility if they are listed on Dmoz.

The only problem is that they can take some time to list the sites (sometimes even 2 years).
