Update! See You at Enceladus has the 51st Skeptics Circle posted, and I have two entries there, including one about the Grand Canyon. That story is still unfolding, and I will have more about that very soon. Stay Tuned.
The Philosophia Naturalis science blog circle has been posted at Highly Allochthonous, a blog whose title is harder to pronounce than "Pharyngula".
Anyway, my entry on the length of the year is there, as well as lots of other cool science geeky readable thingies.
