To celebrate the fast-approaching 500,000th reader comment, ScienceBlogs is running a contest.
To enter, all you need to do is post a comment on any of the blogs in the SB network, using a valid email address. Alternatively, you can sign up to the new weekly newsletter.
When the 500,000th comment is posted, the contest will be closed. One email address from a comment posted at around that time will then be randomly selected.
One lucky reader will win a 5-day trip to the world’s greatest science city, as voted by you. (Cambridge, U. K. currently tops the poll.) 50 runners-up will receive a stylish ScienceBlogs mug.
