I did some casual analysis of data I collected for a small set of queries, and the exact opposite seems to be true - eHow saw substantial increases on many queries following the update. It's possible that this is because smaller sites above it were wiped out in the update, and my set of queries is very small - but it's clear that they weren't hit negatively. This update seemed to have a much larger impact on user generated article directories than it did the new-wave content farms like eHow. That ezinearticles and Hubpages finally got hit doesn't surprise me much, because they are frequently exploited as a source for followed links by site owners.
