I found those comments to be the most helpful "official" remarks so far. The newly mentioned concept for understanding the Mayday update is "content farm" -- Matt repeated the phrase several times and that's apparently one of the key targets. I get it. I've been at meetings with other web marketers in the past months where the topic came up... a lot. We wondered when Google would put content farms in their sights.
But there's still some trouble in paradise. I'd agree with others here that this new algorithm element is still a way off from being perfected. However, since May 3 we have been seeing ongoing tweaks. Some rankings that were incorrectly nailed, false positives in other words, are now seeing their traffic rebound. In addition, I still see some content farm style sites getting way too much traffic.
Matt mentioned some other targets of Mayday - such as sites with too many stub pages. So there is some new detail and food for thought in this interview.
