even if it *does* work, I suspect it won't work very long
i am a little more optimistic about it than you are... hubpages subdomaining strategy isn't really a trick to get google to think that low quality content actually is high quality content.
if a site with 100% crap splits up that crap into subdomains, then all 10 subdomains will get pandalized the next time the data is re-run.
if panda really treats subdomain content separately, then one would expect some of hubpages' subdomains to get out from panda, while others stay pandalized.
all the subdomaining strategy does it so immunize the good stuff from the bad stuff.
