Thanks for sharing your thoughts. The Steemit system is based on principles of anarchy and it is generally valued to not control user's behaviours or thought patterns. This is part of why I suggested simply adding a metric and symbol into the system to show the values involved, rather than actually adding any rules or changes to the way people can vote. I don't know if an idea such as yours would benefit the community or not, but I do know that many people would complain about it.

The issues already raised in this thread regarding penalisation of small communities who vote together on their own interests, would be particularly problematic in your model. My intention was not so much to reward random voting, but to simply allow users a way of identifying quickly some useful information about profiles they examine. I don't want to penalise people who only vote for a small range of profiles, my intention is more to simply promote the thought of the benefits of being more social and engaging with more members of the community.
