Why? Until bots are self-aware, bots are just another form of users using their own stake to vote how they wish, and we fully support that.

Okay, I'm in agreement with you there but the why is vandenberg saying:

The reason we are choosing to do both at the same time is to help human users a little bit against bots

Why propose something that is expressly intended to favor some users over others (and has the indirect, perhaps unintended, effect of favoring users who sign on for five minutes make a few votes and sign off over those who particulate a lot more)?

Another negative consequence of reducing the vote target is that voting will become a lot less casual and social because people will become more aware of their vote power being depleted. The most intuitive voting system is like that on facebook, reddit, etc. where you can make as many votes as you want without 'running out of juice' (equivalent to an infinite vote target). Obviously we can't do that but reducing the vote target is moving a lot in the opposite direction.
