The second lowest common denominator activity is curation (smallest unit of work imaginable).
I guess it depends on how you curate. I curate a music contest called Steemit Open Mic and can assure you it is not the least amount of work possible. It's turned into my full-time job and I'm working my ass off to build a huge, engaging community of musicians on the Steem blockchain. About 8-hours and many days more to do so.
~50% curation rewards.
Can you clarify on this? Are you proposing reducing curation rewards by 50%?
Seeing how I do not upvote myself at all and make my rewards upvoting others and building community engagement, that would not be something I could get behind.
However, all your other points I'm onboard with.
There are only two kinds of voting effects: one is curation, another is self-voting (and trading, which is the same). Just saying curation has at least a minimum amount of work, the other does not have this. There's no way to properly measure hence the statement.
~50% curation rewards is not reduction, it's increase from the current 25%.
Thanks for the clarification. In that case, I'm all for every one of your points.
