Campfire is a place where published items with the most participation go so that everyone knows what’s hot. The more people that collaborate around an item the hotter the fire gets.
Campfires get started when a published item in the Explore section recieves a high rate of participation from other members.
Stoking is a form of fire starting. When you stoke an item on safarious you’re basically promoting as a campfire worthy. Stoking has a higher value over comments and views taking place on an item.
The more stokes the higher the chances an item will catch and turn a campfire.
