Twosides is exactly that: a plugin that list your opinions or views on two separate sides. Call them anything you like but for lack of spending all day to create this monster we call them Opinions. Twosides has a few requirements but that is part of what helps to make it unique.
The basic premise is for a blog to contain a subject matter in a single post which, can instill a wave of comments that are split into two groups as responses to the single post. Pro/Con, GreenDay/U2, Mom/Dad, Product opinions, Positive/Negative Reviews…. endless possibilities.
