I think SM is a fair excuse for a fall in engagement, I'm there a lot too and I know my numbers have dropped.
With vote values so low, there is a lot of dust being scattered. Apart from voting on posts and not comments, there's not much that can be done about this. Let's hope 2019 sees a resurgence in prices...
It will be very nice when the price does surge, and when it does, I plan on going on a voting spree. I feel so deprived lately, having to go 100% and pretty much fore go the comment votes, which I liked to give. Oh well, price will rebound, it is just a matter of when, It has after all been down in the penny range before and climbed back out, so here to penny stock explosion.
