Leah of Unequally Yoked has a cool experiment going on:
In a conventional Turing Test, computer programmers try to write a computer program that can pass for human. In the Ideological Turing Test, atheists and Christians test how well they understand each other by trying to talk like each other. All the entries in the atheist round are collected below, and you can click on each link to read the entry to decide whether you think the author is sincere or shamming.
Leah is also participating in Blogathon, so that should be motivation to show her some support!
