The phrase refers to online communities on a popular social media platform where individuals discuss and share experiences related to alternative, often age-restricted, content. It specifically points to subreddits focused on individuals aged over 100 years or content relating to that age group. This can encompass discussions, images, videos, or other media. As an example, an user might post a discussion about remarkable people over 100 years old and share their stories in that subreddit.
The interest in this specific content stems from a variety of factors, including curiosity about longevity, historical perspectives offered by individuals with extensive life experiences, and a general fascination with the aging process. Such forums provide a space for sharing information, connecting with others who share similar interests, and documenting perspectives that might otherwise be lost. Historically, the online aggregation of niche interests has been a defining characteristic of online community formation.
