# Monthly Recurring Relationships (MRR) An idea of [[Rosie Sherry]] inspired by [[Monthly Recurring Revenue (MRR)]] It's a key metric for communities, where the number of members is much less useful and relevant than the number of conversations going on. A huge community with zero activity is much less valuable than a small community with high activity between members. As Rosie says, "[[Community is about growing at the speed of trust]]".
