changing to 50/50 may well end up being a disincentive for content creators. Why should someone who places a vote get half when it is the creator that has put the time and effort into it?
I feel exactly the same way, especially when spending an hour+ or more on a post as I typically do.
In the end, it will encourage larger users to vote for more content and likely to smaller users. This would be a great thing. It will also encourage more people to vote in general. Is it perfect? No, I don't think we will ever see a perfect balance on a platform that provides financial rewards for creating content.
The goal is to encourage manual curation meaning good authors and content providers should be seeing higher rewards. If this happens, the value of Steem will rise via loop of attracting more great authors to the platform and viewers following them with a want to support their favorite authors. We all agree curation isn't working right now? It's not worth it for those with small SP and curiously same applies to whales also it seems.
We have to start asking what those who decide to not join Steemit think and how can we fix it? Main reason probably is that currently we are not rewarding the best content with highest rewards or even trying to find it.
