This is the bi-weekly visible open thread (there are also hidden open threads twice a week you can reach through the Open Thread tab on the top of the page). Post about anything you want, but please try to avoid hot-button political and social topics. You can also talk at the SSC subreddit or the SSC Discord server – and also check out the SSC Podcast. Also:

1. Thanks to everyone who made it to the San Francisco meetup today, despite my terrible directions and wild underestimation of the size of the park in question.

2. The Register of Bans now has a section for people who are banned from meetups. In keeping with the name of this thread, I won’t explain. If a banned person shows up, I’ll assume ignorance and ask them to leave. If they refuse, I may have to publicly announce the considerations that made me add their name to the list, in order to keep other meetup-goers safe. Please don’t make things reach that point. Thanks to the people who reminded me I should do this.
