To be fair, with a website as huge as reddit, a 25% or even 50% decrease in user activity probably won't be that noticeable from someone like us. Instead of 2 million posts a day, it's not now 1 million. Or instead of 500k, it's 250k. None of those are knew we could feasibly differentiate.
Maybe if you sit on r/all and keep track of how fast new posts are moving, but even then, the algorithm may still just move the same number of posts up and down the main pages. So even then, it would be hard to tell if usage is down.
Now obviously there's no way it's down that much. It's significantly lower. But I'm just saying even if we pretend that it was down that much, it would look like business as usual.
Also, either way, I'm still glad to find this place. It feels nicer and offers what I wanted in a way reddit couldn't.
