numbers speak for themselves
Unfortunately from what I can tell the numbers haven't really changed either way after the last hard fork. Continuation of the same downward trend on most metrics, which makes it all very "ho hum".
The one clear change in terms of numbers is a modest increase in the amount of powering up. I'm not sure what to make of that beyond the observation. If there are any indirect effects, they're not obvious.
Considering that these changes were supposed to help with retention, I wouldn't call a continuing down trend in almost every metric expected. These changes were supposed to help turn the numbers around. I will admit that it is likely still too early to say for sure, but the early returns are not good.
Reasonable assessment.
