/** # of Peers
*
* A new object is created for each cell, so that we can listen to the
* scrapes and update individually (and only when needed).
*
* Total connected peers are left to update on INTERVAL_LIVE, as they aren't
* very expensive. It would probably be more expensive to hook the
* peer listener and only refresh on peer added/removed, because that happens
* frequently.
