Yes, in Japan the trend seems to have shifted back toward in-person events. Most meetups and conferences I see now are offline rather than online, definitely more than a year or two ago.

Definitely less than before 2020, but in the meanwhile, I built Tech Talks Weekly https://www.techtalksweekly.io/ where I send out all the recently published conference and meetup talks every week.

Our local Linux group meets every month. It has become far more general tech focused but still there is always something new that gets demoed. https://humlug.com

Almost never now, and I used to go to lots. In fact I've launched https://opentechcalendar.co.uk/ to try to promote virtual tech events that include community participation instead.

Not unless I'm forced to. Even before the pandemic, it was really hard to justify the time and expense in attending these things.

I've tried several times and never understood what i was doing there...
