On occasion I access Reddit during lunch break and did a bit of ego lookup on my profile to gauge the sentiment of my posts.
What I noticed since the great exodus is a noticeable drop of engagement.
At best I get 2-3 upvotes on posts that don’t have that many comments.
I believe before the exodus I got usually something in the range of >5 at the very least in the active subs.

So this really checks out.
