I propose a simple modification to this section (bullet 4):
as long as they are not about:
- Actions of individual characters, rather than elements of the world they inhabit
- Character building
- Elements of plot
- Facts about the real world, or historical or modern events, except when provided as examples or comparisons in the construction of an imaginary world (consider the History or respective subject-specific Stack Exchange sites)
- General writing or storytelling (consider the Writers or Role-playing Games Stack Exchange sites)
- Software that doesn't directly relate to worldbuilding (consider the Super User or Software Recommendations Stack Exchange sites)
