Hi,
TLDR: reply to me (off-list) if you would think Scrum of scrums is still useful.
I've been sending Scrum of scrums[0] mails to wikitech-l list since 2019-03-20[1]. The meeting has existed since 2013. I haven't done any proper research, but a quick look says the number of participating teams is decreasing significantly.
Quick sample, the first meeting of July in years 2014-2020.
2014-07-09 14 2015-07-01 12 2016-07-06 18 2017-07-05 16 2018-07-11 18 2019-07-03 16 2020-07-01 8
