I saw this article (http://www.cbc.ca/technology/technology-blog/2009/07/moon_landing_space_anniversary.html) at No. 3 on the front page at around noon CST. By 1p CST the article has dissapeared.<p>My guess is that the link was flagged and taken down. What was the criteria behind this? I am not advocating for the article but just trying to understand the rationale behind this step.
