The first time was a huge hit:
Far exceeding my wildest expectations, this became a truly worldwide celebration, featuring more than 250 posts in 11 languages! Sagan fans are truly cohering into an online force to reckon with.
Make your Sagan-related posts before December 20th, let Joel know through his site or via email, and he’ll include your link on his anniversary meta-post.
Good reading will be had by all.
