There's way too many users who use witness voting the way they use curation, i.e. unvoting because they disagree with something a witness or someone involved in the witness does with curation (upvoting & downvoting) and often sit there with just 10 used witness votes or like to play politics and using their witness votes or proxies as a way to attempt to garner upvotes. These are all very childish things to do, we're talking about the security of our blockchain here so set aside those issues and vote for the witnesses you know have the best intentions for the blockchain in mind or proxy to someone you trust is up to date with who he votes for and uses all 30 votes.
