It's impossible to be listed in DMOZ and have no more backlinks. After a few months, you'll get backlinks from plenty other directories affiliated with DMOZ. And you're likely to get natural backlinks before Google toolbar update.
That's correct of course.But doesn't affect my conclusions as these other backlinks would act as a further PR source increasing so my PR. Instead,I had a PR 3 from at least a PR 6 page (just DMOZ)... And zero outbound links.
I'm happy to see ,instead,that you're totally agree with my opinion as regard to the fact that DMOZ doesn't represent any "preferred pass" to Google.
