"Which means more voters for you as an author, which you would not get before."
Yes, more voters, but still the same or even less rewards. Nowadays many people (including even me) are upvoting posts with less than 100%. Mainly because of the new reward curve. Sometimes (when the upvoting efficiency is low) I earn the same amount of curation rewards with a 100% upvote and with a 50% upvote. But sometimes the efficiency is more than 100%, and I earn much more with a 100% upvote than with a 50% upvote. Unfortunately I don't know what (or which) makes an upvote efficient.
"Also the 50/50 is in favor of curators, so you should get more profit from your curation efforts."
That is true. I noticed that my curation rewards are increased.
" I don’t get the “upvote values are halved” remark. Did I miss something? :)"
I don't know by which HardFork (21 or 22), but my upvote value was dropped from $0.008 to $0.004 for some time. Maybe it was a bug. I checked my latest upvotes on SteemWorld now, and nowadays it is dynamic. According to SteemWorld, my 100% upvote (on 100% voting power) is currently worth $0.006, But I checked my latest upvotes, and my 100% upvote varies from $0.004 to $0.01, so my upvote sometimes worth even more than the displayed amount.
