Does it make a difference? Does its capacity for change depend on how many readers you have? How does it measure in efficacy compared to writing letters to the editor, sending complaint E-mails, protesting with signs on the town green, marching in yearly celebratory parades, boycotting, writing sarcastic graffiti on ads, making Web comics, praying, delivering sermons, donating to fundraisers, yelling at your TV, lobbying local/state/national government, etc.?
