I have posted 4 links to dmoz. One of them appeared after a few days ( omg, lucky me ) and others haven't appeared at all. Also, I have read on other forums that if you pay some hundred of $ for the right people, you may get listed in the dmoz immediately. They are corrupted. For example, there are only a few sites in the category, which are total crap and they can not add your site, because editors of the category own that sites...
You can read a great many things on the internet, but only some of them are true. Editors who accept payment are promptly removed, and webmasters who offer payment risk having all their sites permanently banned. I know what I'm talking about, as you can see from my signature, but you can believe me or not, of course. Is it worth taking that risk to corrupt the process? From DMOZ Social Contract:
Anyhow, If Dmoz is good or not wont affect G and other SE's, I doubt G count those links no more, Else it has very low weight.
