What weight? I thought the consensus was that Google was not giving any extra weight or very slight weight to a DMOZ listing.

Google aren't stupid. They do a lot of testing. If they give extra juice to any particular link from any particular source, I would assume they have tested it and on the balance of things, a 'global' better search results are served up to the searcher.

Have you ever consider that if Google does give extra weight to a DMOZ listing (and I not convinced that they do), that the very reason that they might do it, is the very reason why so many webmasters complain about it? Think about it.
