You might just have named the concept upon which Monica bases.
- meta: it's interesting because having a word somehow 'creates' a concept in our minds, easier to think of and discuss I guess.
- topic: the concept is truly interesting, and you 'get it' when reading Monica's marketing pitch for sure. But the way you name it makes it a category, and when I add up that the one feature of Facebook that even non-users still come for is Groups... somehow this all hints at the aforementioned category.
