You all are right, but there is something important - there are low number of directories, which are quality. I mean quality directory for me is directory with do-follow links, many categories, development by newest trends in search engines and good control from the webmasters to this what kind of sites will be added to exact category - they have to be related to this category and with close keywords and content for the best possible evaluation from spiders.
Here I'm trying to select this kind of quality directories and to create useful information list: http://website-promotion-costs.com/f...e_directories/
By the way, if you found other quality directories, which aren't in this list, I'll be glad if you share it here.
I hope this reply will be useful for other visitors.
