Because it’s a slow day here and has been raining since morning, I figured I’d do a bit of counting myself. I did a quick hand count of how many of the “600+” researchers have been actively answering questions for the past 60 days.
Of those, 54 were active in the last 30 days.
Of those, during the last 30 days:
1 Answered 75 questions
1 Answered 50 questions
1 Answered 44 questions
10 Answered 20-30 questions
13 Answered 10-19 questions
The rest answered fewer than 10 questions apiece.
These numbers are very much in keeping with a similar count I did about 2 years ago. I no longer have the exact numbers, but I remember the total number of active researchers being just around 60, with a small subset of those picking up a high percentage of the workload.
I leave it to commenters to decide what this all means …
