There is a huge controvercy about the date on which Eliezer Yudkowsky will tweet the word "rationalussy". E.g. https://manifold.markets/SG/will-eliezer-yudkowsky-write-a-twee and https://manifold.markets/JosephNoonan/will-eliezer-yudkowsky-tweet-the-wo.

This market will resolve YES if he writes a tweet containing the word "rationalussy" on the second to last day of 2023 (CT).

If "tweeting" will be renamed to "xeeting" or similar, it still counts.
