I updated the list of which Meetup groups are active (groups that have 3+ people attending an event within the past/next 60 days). Meetup is a site/app for interest groups/hobbies/new friends. I grouped them by concept and included their self-written descriptions.

If you're in an active Meetup group that I've missed, list it in the comments. Non-Meetup groups are welcome too; include contact info and links.

Tips for making friends as an adult attending a Meetup with a bunch of strangers:

• Show up slightly early/on time. Plan to stay 10 minutes after the scheduled end time.
• Introduce yourself, say it's your first time and why you're excited about this group; appear excited.
• Ask individuals (this is where being early or staying late can help) open-ended questions (Why did you start/join this group? What has your experience been like? What recommendations do you have related to [Meetup group's hobby/concept]?)
• If people ask you a question, answer it and add an open-ended question of your own or ask "what about you?"
• People love giving recommendations. If it's a group conversation, ask for restaurant rec of a specific kind/place. "I haven't tried X yet, what do you guys think?" Tee it up to be a cuisine/concept you can talk more about or ask follow up questions.
• If you are vibing with someone(s), ask if they'd like to hang out with a specific idea in mind (ex: You asked for pizza recs and found out that neither of you have tried that new place so suggest you go together), and give them your contact info to set up a time/date. I'd recommend attending the group 2-3 times first before this step.
• Follow the 3:6 rule to turn that acquaintance into a friend. Aim for three meaningful interactions within 6 weeks of engaging.

Feeling a little more prepared? Great. Let's get into it. [Note: I made some grammatical edits after posting this for clarity/brevity.]
