So, between yesterday and today, my "People Reached" metric on SO dropped by ~13k. I believe I was somewhere in the range of ~906k and now I'm down to ~893k.
Sure, it's a (wildly) fuzzy metric... but barring some change to the algorithm, I wouldn't expect that the number of people I've "reached" could decrease. Certainly, I haven't noticed this behavior (until now) since the release of this feature.
So, three things:
- What, specifically, could cause this? User-deletion/hard-deleted posts?
- Is this behavior intended? bug?
- Is there any chance of developing around this going forward? It seems like there's already an exception for rep. Can that exception be applied to people reached as well? feature-request
For reference, Jaydles explains the feature in this post. Scroll down to the How it currently works (and why) section.
