Please do not vote on any answers to this post during the Nomination phase.
Voting - January 1 - 6, 2020
On January 1, this post will be edited to indicate that the Voting phase has begun, and the featured tag was added.
During this phase, everyone is invited to vote on the answers to this post however you see fit. Upvote (or downvote, I guess) as many as you like.
The answer linked in the highest voted answer to this meta post will receive a bounty of 300 points after completion of the event on January 6, 2020. In case of a tie, the distinction will be shared, and the prize will be split.
