Yeah, I've been thinking about that. I'm curious to see if Hubpages continues to be "recovered" using the sub-domains. They have gone through at least 2 Panda runs since reporting such (post sub-domain conversion of existing content). That content was not penalized in October (and has not undergone significant revision).
Problem is needing more info on what was targeted on Oct 13/14. I have seen 0 negative impacts from the Nov 3 update (so far).
Interesting times I reckon.
