Did the current pandemic had an impact on traffic and posting on IPS? If so, how?
Starting around the 9th of March 2020, it seems that the current pandemic did, indeed have a significant impact on IPS. More specifically on the number of questions and answers posted.
Here are the data for IPS Main:
And here are the data for IPS Meta:
From those data we can clearly see that the number of posts posted has seen a significant drop. We have more or less two times less questions/answers being posted each week on IPS main. As for IPS meta, it's even worse. Since the "beginning" of the pandemic (let's say it was the 9th of March), we only had 5 questions asked. It's not even one per month.
As could be expected, the number of votes also decreased significatively on both main and meta (if there are fewer things posted, there are fewer new content to vote on).
The number of pages viewed (on both sites) decreased as well. However, (thankfully) the number of visits and new visits on main remained more or less steady.
