r/ParadoxExtra is a subreddit with 78k members. Its distinguishing qualities are that the community is large in size.
The other reason is that the central focus of the story (perhaps I should have left in the 200 word summary) was how a seemingly insignificant event that occurs during the EU4 timeframe, i.e. the British landing in Quiberon (compared to say, the fall of Constantinople, discovery of the new world, reformation, enlightenment, Waterloo, etc) could have drastic differences on Europe as we know it today.
