Thank you for your hard work; and thank you for the transparency.  I will have to take some time out and look at the new bot source code so that I can fully understand all of the changes in detail but overall this seems like a good change.

edit:  I do have a few misgivings about letting the moderators have the power to influence how much a contributor should get.  By giving moderators the power to change the weight of a vote you are also letting bias and subjectivity into the equation.  I guess we will have to see how things go from here; though even before this change I did notice that the scores on my posts varied based on who was moderating them.
