I just did a Twitter Search on the words "culture" and "faith". Interesting results. I think you can see Andy Crouch's postures come out so clearly. Here are a few of the Tweets and, in green, my thoughts on which Posture is represented. You can hear about these in Andy's talk at Grace Point on March 15.

jrminkel: "in the U.S. the default for culture is a blind faith in science, rather than a war on science." Condemn
AndyGroenink: @jasonmitchener 6 page assignment on case study of reaching another culture, I picked the Muslim faith Critic
heathr: And yes Tom u can be Jewish and gay. Maybe not the Jewish your parents get, but your faith is yours + yr culture is big enough for u! Consume
cjcasciotta: was interviewed by MTV about faith and American Idol. I hope I got the point across that the church should create culture, not copy it Create
sumapriapus: Watchmen: This is why conservatives have a tough problem today. The pop culture undermines faith, family and freedom. Condemn/Critic
brandonrae: [ HIP-HOP ] [ PANACEA ] [ STARLITE ] [ Enjoy, and have faith in theculture that I love ] ♫ http://blip.fm/~2v9zv Consume
I didn't see copy there although on person talked about how Christians should not copy culture. The rest were all there. I'd love to hear your analysis of these tweets. Maybe you could search again and see if they all still show up.
