There is only one thing on the list that is not completely obvious -- dmoz still matters. Is it possible? Sure, it's a valuable list of sites touched by a lot of care and bureaucracy, but does anybody who wasn't online 10 years ago know about it?
I forgot all about it until I saw this, so I guess I'll check back sometime in 2013.
These directories are valued by the search engines because all listings are not automatically approved, so there is a certain quality aspect to the listings. While the directories don't send very much traffic, they do pass trust to the sites they are linking to.
It can be tough to get a DMOZ listing, particularly if the category you are applying to doesn't currently have an editor. However, it's worth it if you can get accepted.
