I am not really sure whether it's a great meet-up place, but I've always found it filled with interesting people and skillfully prepared libations: The Interval Bar at Fort Mason, the home of the Longnow Organization (https://theinterval.org/ https://theinterval.org/). Events at the Computer History Museum are often worthwhile even though it means a trip down the Peninsula to Mountain View to visit. https://www.computerhistory.org/ https://www.computerhistory.org/ The museum itself is interesting as well. The Internet Archive (https://archive.org https://archive.org) is home to an active community intent upon building an archive of information, especially digital information.
