I just read this blog post about the change in traffic due to the pandemic. It's very interesting and I'm grateful to the people who took the time to write it. However, it only talks about SE sites that have seen an increase in traffic.

So, I'm wondering if some SE sites have seen a drop in traffic due to the pandemic (my guess is yes). Which are those sites?

Also, are there some SE sites that haven't been affected at all?

And if someone could provide a list of all the SE sites and how they have been affected in traffic/participation, that would be very nice.
