I think you'll find running a NN smoothly 24/7 takes a lot of time and skill, and ya know, if you pay peanuts ...
Community run nodes are a good idea though, I agree with that!
I'm not saying running a NN is easy, but ~1500 KMD easy mining returns per month is a great income for a sys admin even at the bottom of a bear market, but what about during the next bull run when KMD reaches the next ATH?
Do the math, NN income could be +15K USD a month in a couple of years (it's almost a certainty with all the recent progress), and as long as the operator stays in the top 50% they never have to face another election, and they get to keep those profits even if they contribute nothing back to the community. They could go fully dark, do nothing extra for the community, and dump their KMD profits for Doge every month and nobody could stop them.
There's a price point for KMD above which NN profits become ridiculous for the work involved, that's why community pools are the way to go, KMD holders get the profits and have the incentive to invest back into the community.
Just hope it's not too late this year, otherwise 2020!
