As I only submit pages to DMOZ I keep a log of:
1. page submitted
2. date submitted
3. which cat
4. no#1 of current listings
5. anchor text (page title submitted)
6. description submitted
7. current page PR
and then monitor log files.
7. anchor and description listed by editor
8. Cat PR
9. add link on the page to directory cat
when googlebot crawls page, remove link.
10. monitor backlinks in AllTheWeb.com when a DMOZ clone appears with grey google bar, submit to google.
11. after each google crawl edit log PR's page and cats, any new listings etc.
12. note when added to google directories.
Although most clones turn out to be PR0 have found many PR4 - 6, a few PR7's and 1 PR8.
All but regional listing in DMOZ cats increased since June crawl and so has many of my pages.
actually both, my page backlinks grow proportional to DMOZ cat backlinks in most instances. The clones point to DMOZ, my pages (as well as my competitors within the cats).
Although other sites listed gain PR as well (and you could say at my expense) the rewards are far greater.
Each month DMOZ back links inducing higher PR some of which is transferred to my pages. My backlinks grow as well increasing my own PR which is transferred to other sites in association.
Even on cats that are PR1 or 2, all it means is "not enough backlinks", you can easily induce PR since clones are a dime a dozen! The best cats therefore are the ones with the least listings, more PR for me and generally faster acceptence in DMOZ.
In general, (although I don't track) I have far more DMOZ listings than any competitor. (some day maybe this will be common knowledge and they'll paid me for all the hard work I did for them for free).
(NOTE: twenty years in submarines allows you to "fathom" things from the bottom up).
