Just for the Hades of it, I decided to search for "rational response" and "rational responders" in Facebook

 I got about 50 hits, including a sizable number of ones unconnected to us, for the first one, but only 2 for the second one.

• Official Rational Response Squad on Facebook - 294 - silver RRS logo
  
• Tha Rational God Squad - 170 - silver fancy cross with "Jesus"
  
• Prayer Warriors for the Rational Responses - 152
  
• Atheist's Against Atheist Fundamentalism - 4
  
• Blasphemy Challenge - 146 - silver RRS logo
  
• The Blasphemy Challenge: Willingly Commit THE ONE Unforgivable sin! - 49 - gold RRS logo
  
• Pray against the "Blasphemy Challenge" - 197
  
• RRS: Bring on your Challenge! BRING IT! - 48
  
• the so-called "Blasphemy Challenge" - 19
  
• My Rational Response - OUR answer to the Blasphemy Challenge - 2
  

 I wonder what a search of MySpace would reveal.
