I do hope this forum can get more promotion from the Godot team, because for starters Reddit is an awful solution as far as finding discussions and projects go (as the threads get buried within a couple of days), and Discord is even worse in this area. It pretty much leads to new threads for every update to every project and the same questions having to be asked again and again. Tags can only get you so far as even they break down as a discoverability tool once there is enough activity.
Far and away, the traditional forum setting is still the best place for Q&A and project threads.
