Voting alone is one thing, but the effects of the voting is another. This is a complicated topic.
In the political world, a vote is a vote; everyone gets a vote and it counts the same as everyone else's vote.
On here, a vote is not a vote, because the more SP you have, the more your vote counts. Basically, it comes down to those with money can control everything. The vote of 1,000 noobs means nothing next to the vote of a single whale. So what are we really talking about here? Are we examining ethics of voting or ethics of the system itself? Are we looking to find a consensus about what is acceptable voting practices or are we looking at finding a way to make the system work for the broader population?
Unless you define your focus, it is difficult to give an answer.
Yes, I want all of the answers. I guess what I personally am after is people spending a couple of minutes wondering how (and yes in some cases IF) their vote is impacting the site.
The users of this site all have different goals and financial means, something I try to do is "Practice how I want to play". (Even when my vote is small, use it like I mean it)
Voting covers all voting including witness voting.
So if you are looking only how we view voting for ourselves, then I would say that there are a few who vote the way the system was 'expected' to run. The majority see voting not as a way to govern the system, but rather to earn an income. This leads to 'gaming' the system and is the source of SPAM and all the other ills that the original intent was not supposed to have.
I'm sorry to say it, but I see the system as not functioning as intended.
