The voting period has ended. Thanks for everyone taking part, and congratulations to cnread, Sebastian Koppehel, TKR, Cairnarvon and Alex B! (The bounties will be distributed shortly. As the fourth place is tied, we are giving out 100 points to the top three and 50 for the two other answers, splitting the fourth price.)
What were the best answers of the year 2020? Nominate your favorites and vote on other people's suggestions! To nominate an answer, simply post it an answer to this question with a link and brief description of the answer. You can nominate as many answers as you want.
The nominated answers must have been originally posted in 2020. To get you started, here is a search for all answers from this period with positive score. The answer doesn't have to be accepted, and it doesn't matter if it has already received a bounty.
Everyone is invited to nominate and vote! After about a month (July 10 or 11, but we make no promise about the exact time), the four nominations with the highest scores on this meta post will be declared the winners. Now that we have four moderators, we've decided to reward an additional answer!
The four winning answers will be rewarded with bounties of 100 reputation points each, from the personal reputation stashes of the moderators. (If the scores are tied, we will reward at least four answers and give out at least 400 reputation in some way.)
Of course, anyone with 75 or more reputation is free to reward any answer they like at any time. Consider this contest also as an opportunity to highlight some hidden gems that received few votes but are excellent in quality.
