But Plato is, actually, relevant to our site. The cave analogy is a perfect description of how we see current social discussion- people understand themselves and others by interacting with mere "shadows" that are not very substantive. Facebook lets you know who you're talking to, but profiles are often more about what that person wants to be seen as than about who he actually is. Our goal, conversely, is to let people strip away the superficial and discuss their real opinions in an unadulterated form.
