Meetup Groups are social gatherings organized through the Meetup platform, which connects people with shared interests. These groups can focus on a wide range of activities, such as hiking, book clubs, tech discussions, or language exchanges. Members can join existing groups or create their own, making it easy to find like-minded individuals in their area. Participants in Meetup Groups typically communicate through the platform, where they can RSVP to events, share ideas, and post updates. The goal is to foster community and encourage social interaction, helping people to meet new friends and explore new hobbies in a relaxed environment.
