Hmm, in a sense I get you Taraz. It's complicated to track down the platforms of many witness candidates you'd evaluate for voting. And certainly it would be even more difficult for people who barely know what witnesses are, if they will be interested at all. How would we convince them to take time and evaluate every witness they vote for at length? That's nearly impossible.
Adhering to common standards may simplify things. But Steem governance will resemble more and more with real life political arena, and it seems many want to go as far from those models as possible. We'd just give birth to parties and doctrines this way.
