We normally see a few new questions per day, and then of those we normally only get what I would call "good" questions maybe 2-3 times per week.
The thing that had kept the site seeming more fresh than that was the Community Bot, which would bump older questions to the top. This would typically happen for maybe 5-7 or so questions per day.
Lately, though, it seems like we don't get bumps like we used to. I've noticed that since about mid-January the bumps have almost completely stopped. The site looks much slower now. If you look at the site analytics, you can see that question and answer posting is on a sharp decline; questions and answers now are about a third of what they were 3 or 4 weeks ago. All of this despite the fact that traffic seems to be about the same.
My big fear is that declining question volume is driving the declining answer volume, and the overall decline in participation is going to start driving traffic away (or failing to attract or retain regular visitors).
Who controls the Community Bot? Was there a change made to the Community Bot? Is there a setting that we, the moderators of that site, can adjust?
