I was only alerted to this fork by way of an unusual amount of success staking all of a sudden. I'd left the node running on the old chain and had fewer stakers with whom to compete for a stake, and on a completely useless chain whose coins will be rejected by the new one. So I guess those who don't realise the fork happened will keep accumulating a bunch of useless, old coins on a dead chain... at least they'll get a lot of them, lol.
