Less Wrong members sometimes arrange meetups to meet each other in meat space. Some geographic areas have groups that do this regularly. This list also includes some virtual (online meetups), See Less_Wrong_meetup_groups#Virtual. Also see: Less Wrong meetup group resources.

A map of individual user locations was created in 2015, but is likely out of date. See also the official list of Effective Altruist groups and the SlateStarCodex meetup repository.
