In August 2019, 29 of the oldest beta sites graduated (in name at least) in an attempt to "mean the end of the monolith we currently refer to as "Graduation" in favor of a well-defined set of small targets to achieve the various elements that made up "Graduation"".
This is now more than six months ago and I wonder what the practical impact was on the sites' activity like visitors, number of new questions, answer rate, number of votes, user happiness, ...?
One could for example compare activity with the six months before August 2019 or use a control group of old beta sites that are still beta (Genealogy & Family History, Robotics, Politics, Sustainable Living, Tridion, Reverse Engineering, Open Data) or graduated sites that have a low number in questions per day (Anime & Manga, Bicycles, Christianity, Quantum Computing, Photography, Movies&TV, ..).
