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)
