This is very subjective answer. Based on only how it looked to me and I could be absolutely off with my view.
I Haven't been around that long, but I lurked actively for maybe two-three years before joining. I think when I joined in 2016, until somewhere around 2018? That's from my experience. I recall discussions at that time about more people coming in than before.
What I've understood from the older residents here, before that KKF used to have more off a smaller community vibe.
At least I felt a marginal dip in the action about 2018? Not a huge difference though. Maybe it's been picking up speed again? And yes probably aided by covid as with everything home related has been more popular than ever before, Like interior design, home gym stuff, cooking, gardening etc. We all need something fun to do while stuck at home.
That's my cautious ball park guess?
