Okay, pick some variables. What do you want to measure to determine the value or importance of differing “public squares” and what criteria would you like to use to define what is and isn’t a “public square”? Personally while I don’t think Facebook itself is all that important as a “public square”, I think they actually have figured this one out and a long time ago at that.
