Just to clarify the ScienceBlogs 1,000,000 Comments contest: the millionth commenter didn’t win anything. Everybody who makes a comment on Scienceblogs up to 30 September is automatically entered in a drawing to win a fabulous trip for two to New York. If you slept through the moment when the millionth comment was entered, you didn’t miss anything and you didn’t lose, necessarily.
So keep on talking. But shhhhh, don’t tell anyone: you only need to make one comment to be entered, and more comments don’t increase your odds.
