This is the weekly visible open thread. Post about anything you want, ask random questions, whatever. ACX has an unofficial subreddit, Discord, and bulletin board, and in-person meetups around the world. 95% of content is free, but for the remaining 5% you can subscribe here. Also:

1: New meetups have been registered in Canterbury, UK and Tallinn, Estonia. Meetups scheduled for the coming week include Los Angeles, Ottawa, Milano, Lisbon, Moscow, Edinburgh, Montreal, Waterloo, San Francisco, Atlanta, Ann Arbor, Rio de Janeiro, Cape Town, Auckland, Berlin, Denver, Istanbul, and many more! As always, check the meetups list for details.

2: Manifold Markets wants me to remind you that this is approximately your last chance to sign up for Manifest, their forecasting and prediction market conference in Berkeley, CA. Guests will include Nate Silver, Robin Hanson, Aella, Zvi, and the CEOs of Kalshi, Manifold, and Polymarket. I’m still figuring out if I can make it but I’ll try my best.

3: Voting for the Book Review Contest winner closes this Wednesday; this will be your last reminder. If you were a finalist, you should have gotten an email from me asking you for biographical details; if you didn’t, check your spam folder or email me at scott@slatestarcodex.com.
