Intriguing idea. I'm for anything that is a forward step in the right direction. When I first started on Steemit, I self-voted because I thought it was the thing to do. Of course I vote for my own content. I endorse it fully...every piece. I didn't understand everything just yet.
Maybe by about post 4 or 5, I had stopped doing it because I saw someone speaking about it in a negative light, and I didn't want to be like "those people".
I recently hit the Upvote by mistake on one of my posts trying to see the voters...and I felt bad. I think self-voting needs to go away, but I think at the same time, new posts shouldn't start at the bottom of the barrel. I don't know what the solution is, but you have my vote for witness.
Lower level post self-voting is just fine, with so few Steem Power any bit will help you grow your account and it will not be frowned upon in any way. This is more for the very large impactful accounts tied with spam, malicious self voting comments etc and very large accounts where a self vote is worth $500 and by voting for themselves can push there content directly to the top, may it be good content or not. The are many fine lines and many different opinions, make sure to read through the comments here and listen to what people are saying and come to your conclusion 😉 good healthy debate.
