Why wouldnt these get PR? If you check DMOZ theres also a ton of sites listed who are hosted at angelfire or geocities. Some are to accounts that no longer exist... I've tried making new matching accounts, but apparently the same "categories" for the directories were no longer available. You know how they do like angelfire.com/category/username... maybe im thinking geocities, but yeah...
I dont know if these would have any value though, because it'd be hard to monetize the traffic if there were any. I dont think those free servers allow ads, but I guess you could just link to your other sites and hope some of the traffic follows through and converts.
