Yeah, I sometimes wonder about those statistics. But I'm not curious enough to invade people's privacy or use any of the other modern marketing manipulations to boost sales. I think if you make a thing and pour love into it, people will love using it, and maybe even want to give you a little money. I've seen this first hand many times and been on both sides of it. That's why I like Show HN, and give apps like JournalBook an honest look, especially when it's clearly a passion project by a single person.

Edit: Thanks for the bspwm link btw, I've been wanting to add a class to Autumn called TileWM (to complement the existing GridWM) but I couldn't wrap my head around binary space partitioning, although I knew that's what tiling WMs usually use. The page you linked to describes and visualizes it really well and now I think I understand it well enough to finally implement it. Although, given the nature of Autumn, someone could probably implement this feature sooner using Autumn itself :D
