Don't underestimate the effort required to keep a notary up and running, and it's only going to increase as more assetchains come online with dICO's. We need reliable nodes, and if you pay peanuts you get monkeys. I hope the pendulum doesn't swing too far the other way, Yes, there are some guys sitting back making good money today who pay a manager to run their node, but early adopters always get those amazing deals, like mining bitcoins in 2010-11.
If we drive down compensation for running notaries too far, and break things, it's actually worse than having a few early adopter fat cats creaming off the profits.
I don't under estimate the work involved, these notaries will generate a lot of wealth over the next few years, it's mind boggling really, and that's cool, I find it all fascinating to watch unfold. I get my 5% per year too, so all good
I really can't see unworthy people lasting too long, the top 30 spots must coĺlectively control a huge amount of KMD between them, and as they don't have to get elected again this time but still have a vote, I suppose some of them could conceivably run again this time and get elected for more nodes, which is fine by me, as it's proof of stake based, and those people obviously want to see kmd succeed.
afaik notaries aren't critical for preventing security problems like dble spending, so concentration of notaries isn't so much of a worry like with bitcoin. As long as notaries are selected by stake and merit, nobody can really complain.
Any early adopter 'Leeches' will get wiped out by pools, or other early adopter whales, or new whales.
