What's Solstice?

Solstice is a holiday for people comfortable with uncomfortable truths and who believe in good. Secular Solstices take place in many cities around the world, but for us New York City is the best place for it. The first Solstice started here, amid towers that reach for the sky and glitter like stars in the night. Now a tradition spanning over a decade, rationalists from across North America - and sometimes further afield- will come together to sing about humanity's distant past and the future we hope to build.

And what's the megameetup?

For a decade now, once a year New York City has hosted aspiring rationalists for a long weekend of skill sharing, socializing, and solsticing. Picture around a hundred people who try to make better decisions and think without bias (or read a lot of LessWrong and its adjacent blogosphere and fiction) in hotel conference rooms for a weekend, leaving behind only memories and pages of scrawled math equations. Timed to coincide with Secular Solstice, the megameetup is a mixing pot of people who have been attending rationalist meetups regularly for years and people who are meeting in-person rationalists for the first time.
