A GitHub Meetup is planned to occur every two weeks in San Francisco, typically at a bar or restaurant, with the initial gathering scheduled for July 16th at Kilowatt in the Mission at 7:30 pm. The event promises a social atmosphere with the first round of drinks on GitHub, encouraging attendees to look for Chris Wanstrath, known as @defunkt, or @mojombo for introductions. This initiative highlights the social aspect of tech meetups, emphasizing the enjoyment of networking over drinks.
