SEMadvance: I'm 5 years and waiting to be listed in DMOZ. The catagory that I need to be listed in hasn't had an add or a subtract in years at my last check. I was also invited to be an editor by another editor; but when I applied, I was rebuked by the editorial board. Yes, DMOZ seems to be irrelevent, however, it is still relevent as far as far reaching links by other directories and to big G are concerned. I still feel that having a link in DMOZ is probably a better piece of
SEO than most changes on a website, and especially better than the now defunct "Links at all costs campaigns" we all ran a few years back.
As far as Yahoo...I still think $299 is a bit steep to be listed in their directory, especially when a site spends (spent) lots on Overture.
