Welcome to the first-ever Mi Yodeya answerathon!
The goal here is to answer as many unanswered, open, non-negative questions as possible and get your answers upvoted (i.e. a net +1). Once the contest starts, you must post every day1 and get an upvote within 24 hours of posting to remain in the contest.2 Once all but one person is knocked out, the contest is over!
What’s the prize for playing, you ask? Potentially, thousands of reputation points, from 10 points for every upvoted answer, plus submissions to our preexisting Best Answer Contest and bounty for old questions.3
How do you play? All you have to do is find a question from this list and post an answer. The more questions you answer, the better your chances of staying in (and the better your chances of gaining rep). In a previous draft, the link was to all unanswered questions, not just those which were from before the competition started. All existing posts are grandfathered in, but take note of this henceforth.
On each day of the competition, I will post an answer on this thread with the date at the top. Once you’ve gotten an upvote on an answer, add your name to the bottom of that post with a link to your answer.
The competition will start on this Sunday, January 20, Erev Tu BiShvat.
Congratulations to Alex on winning the Answerathon!
You all can go celebrate over here.
1”Day” starting and ending at midnight UTC.
2Friday and Saturday are counted as one day, and, by extension, any answers posted on Friday get 48 hours rather than 24 to get an upvote.
3What’s the prize for winning, you ask? Uh, um, uh, bragging rights?
