As suggested in another meta post, let's do a Physics Stack Exchange "best of 2016". There's a nice precedent for this in the Puzzles and Code Golf site.
Reward and draw attention to some of the best content our community has created this year.
Have fun :D
Establish categories. Each answer on this post should name a category for which we'll later vote on the best-of. For example, a category could be "Best answer by a new user (i.e. made their account this year)". Voting on the categories will last until the end of January 10. We do not specify a fixed number of categories, but based on the Code Golf example I estimate we'll have five to ten.
Vote for the winner of each category. We create a meta post for each of the top-voted categories. Under each category meta post, users nominate candidate questions/answers/etc. by posting a answer with a link and a short explanation of why the linked item should win the category.
Select winners. Whichever answer gets the highest score wins the category. Voting lasts a specified amount of time, which I or someone else will decide soon.
(optional) Award prizes. Each winning item might receive a prize in the form of a bounty! If you're willing to award a bounty for a particular category's winner, leave a comment under the category nomination in this meta post.
