I was gone for a while and when I came back I noticed 5 or so of my witnesses I was voting for were defunct.

That's sad that there are lots of inactive witnesses in the higher up spots. I would much prefer that active witnesses who were contributing to the blockchain received the top witness spots.

I would be okay with a vote decay as long as it was not too confusing.

I am not very knowledgeable about proposals, how they work or how they might be abused. I'm glad there are people like you guys who know the inscand outs, and you still care.
