Cool. On Sequiturs each step in an argument is called a proposition; a proposition can be used in an argument as either a premise or a conclusion. Propositions are sort of the atomic element of content on Sequiturs, since they can be reused across arguments. Soon, propositions will have their own pages, so that users can efficiently explore all the arguments where the proposition is used, as well as vote on whether the proposition is true or false and discuss that.
