Post generally interesting content, try to stay away from celebrity's personal affairs (i.e. tabloids)
Make sure your fact is TRUE!
Provide a source for your facts
Nothing misleading/over the top. Don't exaggerate the truth or stretch it in any way
Users must be able to tell what the fact is about without clicking on anything
If a post contains sensitive content please mark it as such (example: gore or nudity)
