Related query results refinements: Sometimes we fetch results for queries that are similar to the actual search you type. This change makes it less likely that these results will rank highly if the original query had a rare word that was dropped in the alternate query. For example, if you are searching for [rare red widgets], you might not be as interested in a page that only mentions “red widgets.”
It looks like this is another step backwards from their overall 'improvements' this year. How long has it taken for them to notice that users are displeased with many search results being filled up with irrelevant junk "Google thought" might be helpful? Search results have become far too fuzzy.
New “parked domain” classifier
Took them long enough, though to be honest I've been seeing less parked domains in their results since last year.
Google since Panda 1.0 can't identify 'original content' if it was smacked upside the head with it. Pre-Panda was (IMO) much more effective at identifying non-original content than Post-Panda. It looks like this blog post acknowledges there is indeed an issue. I would really like to see some work put into this part of the algorithm over the coming months.
