Hi
I apologize for being late to comment on this post regarding a change to the author/curator reward percentage.

I would like to propose a solution to this issue, at least a theoretic one, using partially existing infrastructure and rules, but also taking advantage of an existing capability in Steemit code, which would allow people to choose to change this split themselves.

After I read this post, I studied some of  the existing graphic interfaces and I found that some of the existing sharing features on Steem-plus and some other graphic user interfaces on other platforms  allow people to change the sharing of rewards on their specific posts to 50/50 percentage of the authors rewards with a single named beneficiary. 
Since the number of beneficiaries and the way the term beneficiaries is defined is written into the code underlying the graphic user interface, it is in theory possible to redefine  beneficiary in other terms, such as beneficiary equals user who comments on my post or beneficiary equals user who upvotes my post. After that the code would define the math formula or algorithm which determines the amount paid to this newly defined “beneficiary”. Most developers would use the existing  code found in the Git Hub library for this algorithm and not rewrite that portion of the code. 
I would suggest incentivizing a developer with JavaScript JS experience to write a code modifying one of these interfaces. 
In fact, it would be interesting to find out if a developer has already worked on some code to achieve this goal, i.e. a way to change the author/curator split and the code is stored on someone’s Github site.
The final pice of such a code would connect to Steemconnect similarly as we do now when defining interactions between our Posting authority and the Steem Blockchain and especiallywhen defining interactions between our wallet and the Steem Blockchain, but it should be doable on a shorter timeframe then the development of a whole new platform, plus the use of code which has already been used in a live environment and found to be stable will accelerate this process. 

I think that in theory this could be done, and it would not require special permissions from Steemit, inc, as it requires only user granted permissions to change the split for an individual user.  I hope I have summarized the problem correctly and explained my proposal clearly. If not please contact me.
