I just noticed that I got my second website accepted into DMOZ on a PR6 page, but the page doesn't even appear to be indexed in Google. Is Google already starting to place less importance on DMOZ by not deep indexing it? I can't understand how a PR6 page can't be indexed, unless it's a temporary glitch.
DMOZ applies throttles to spiders that hit it too fast: http://www.dmoz.org/robots.txt so googlebot may take some time to traverse all 590,000 category pages and find the recent changes.
If the page is not indexed, it will be indexed by Google soon. I noticed even really deep dmoz categories are indexed by Google. Google is just doing a major serps update, so it should pop right back soon.
