As for the witness voting there are things that can be improved there too, but it is representative to the ecosystem which is based on DPoS.
As for the proposal system, there is definitely a need for improvements/changes to the way proposals are presented and made visible to the public. So that all proposals can be equal in opportunity.
We no longer have a centralized body or committee deciding upon the dispersion of funds that are allocated for the further/future development and expansion of the chain and all things relevant to the chain.
Hence it is dependent upon the community/public.
Thus there need to be adjustments made to suit these needs and further ensure decentralization.
In the past I stated that there is no need for anyone to fear the public, we should all embrace an all inclusive platform for transparent, open and public discussion where the constructive individual is valued and respected.
Unlike in real world governance, where the governing bodies tend to fear the public and keeps dividing them into groups and "paying them off with their own money" (from taxes etc.)
We do have a huge potential to set things into motion that could literally show the world how it can be done and how it should be done. With that type of approach and attitude, we will get the support from millions of people from all over the world.
Again, looking forwards with the wealth of "hindsight 20/20" to back it!
