As of the time of writing ([[2020-11-25]]), the Agora works exclusively on a pull model: it constantly tries to pull updates from all participating [[digital garden]]s. This is simple and works well enough but might not scale.
Pushes could fix this. Garden owners could set up some sort of push protocol so that, on each garden update, their note taking tools or their git host ([[github]] is currently the most popular) let the Agora know that there are updates to be pulled. By doing this, they might get better refresh latency.
