This looks very cool, a nice idea to do. Centralized lists have always helped me in finding the tools or information I am searching for. One thing to note would be that instead of adding a new comment each time, to instead edit your original post with the new links. Also, as more resources gets added, dividing them into section would be a good idea as well. When I have the time, I'll look through my bookmarks and send you resources I have gathered together that would fit here. Would you like only ones that would work for cartography, or world building in general?
