Thank you for your feedback @eirik

many Hivers don't take witness voting...

While I agree with you that the lack of involvement in witnesses and proposals vote is sad, I believe this is more a "user education" than a "blockchain and its rules" issue.
It takes time for people to deep dive into all the blockchain mechanisms and some are not even aware of their favorite (d)app is running on top of a blockchain, which can also be considered a good thing.

There should also be a witness voting decay.

This is being currently discussed.
