I generally agree with you, but have some different thoughts. To explain, I need to refine two points of your statement "the whole point of steem is to reward others with your voting power".
- "To reward" is not a perfect term in accuracy. Actually, it is reallocation of public resource (like which project we should support with tax money) via collaborative decision making. But reward can be correct in broader sense IMO.
- "Reward others" is not correct. The correct description should be "reward contents", not people.
So, in my words, "the point of Steem is to spend community money on contents, which are perceived to potentially generate values for the community, via collaborative decision making process with voting power."
Back to self voting, I think self-voting can be cast if an author evaluates his/her content worth to be rewarded. There is no reason to exclude the author from the evaluation process, since he/she is also a stakeholder of Steem.
However, the problem of superlinearity is when one has very big voting power, which is greater than average upvotes(in VESTS) of all other posts. In this case, the self-voter can earn more than his/her stake shares. Smart bots also follow this large voter while other minnows feel disappointed. Consequently, collaborative decision making process is hindered.
In the linear system, everyone's vote will be treated in equal weights, regardless of being whale or minnow, and this will facilitate collaborative decision making process. There can be some more self upvoters, but I think it is okay if they think their posts are worth to get it. Surely, others can downvote if they think the posts are overvalued.
The key for Steem is collaboration. Equality in vote and weakened bots influence are good move IMHO.
If there is a proposal to allow people to use all their power in a single vote, would you be in favor ? If not why?
I am for it, but not in a "single vote" form. I'd rather want to see "point-based" vote, as suggested in https://steemit.com/brainstrom/@clayop/brainstroming-new-design-for-voting-power
I'm sorry to say but if you are for it ( in whatever form) then you don't understand the implication . If people can use full power in 1 single vote they will write one post per day and give all the money to themselves.
The fact that currently users need to upvote 200 post to use their full power is what protects the whole system against self-voting.
Small clarification here: You currently only need to upvote 40 posts per day. It is 200, but over a 5-day recharge period. The proposal is to reduce that somewhat. I don't know what number would be used by 10 has been suggested.
I don't even think self-voting is all that bad anyway. Overall the linear curve makes the system a lot more like tipping. Assuming everyone voted, what your votes would be doing is assigning is a share of the redistribution of your own stake. So if you don't see anything going on that you believe adds enough value to want to redistribute your stake, then as far as I'm concerned go ahead and keep it. Let people bring more value or make a more compelling presentation if they want to earn, rather than constant shitposts just because, well, something has to get the money. No it doesn't.
I think that's incorrect. I did a test yesterday and upvoted 65 times ( full power) and my upvoting power went from 100% to 72% and got fully recharged when i woke up 12 hours later.
You are missing another important point. What you said can happen but it cannot always regarding other's behaviors(downvote) too. The important point is that linearity makes others participation easier and reducing bot effects.
Nobody is going to waste their voting power to downvote random people that upvoted their own work and even if they did that's not the kind of system we want to promote where everyone downvote because everyone upvote themselves. It creates a very toxic atmosphere. Linearity has very little to do with self-voting, I have explained multiple times how the curve does nothing to prevent self voting.
The problem you want to solve is a non issue, hardly no one has ever complained about bots having supposedly and edge over manual curator, however if the single vote limit is increased then we create a self-voting and vote concentration problem which will discourage curators and users to diversify their votes and vote for other content than theirs.
