# 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]]".
