Well, I am excited to see the impact of this. These days there is no shortage of tools that monitor SERP fluctuation, and if this update brings about _significant_ impact it will be talked about everywhere. And I fully expect spammers to go ballistic once their content gets obliterated.
Did they go ballistic when Google introduced the Panda update in 2010, killing many of the the web-scraped, machine-generated blogspam that was poisoning search results? No, they moved on to fresh territory like Youtube, gaming the recommendation engines. And they eventually came back to the web to poison results with hordes of awful 'best bicycle for fitness in 2022' type afilliate marketing sites.
