The only important thing about DMOZ is it's the only way to get into the Google directory, which is the thing that actually provides a big boost for your website in Google search. Otherwise DMOZ is worthless.
NO YOU DON"T Apart from the rest of your post, you are wrong about this point. 5 years ago yes but not now. Google ignores links from clones and clones by itselves. NO, IT DOESN'T Google stop using dmoz in SERP long time ago 3 years ago you would see in search results dmoz/Google directory info but it's gone and Google now ignores dmoz link in it own directory. The only backlink you will get is from dmoz itself. Guys, get your facts straight
