Chicago Bloggers is a marvelous Web site. The site charts bloggers based on each blogger’s specific location in the public transportation grid of greater Chicagoland. Bloggers list their blog not by content type, but by CTA stop or Metra stop. Thus, one can hear what the neighbors are blogging on about. Or one might make an inquiry into the “blog tones” of a certain neighborhood, and see how they differ from one another.
