A little over a year ago we had great fun with Lurker Day, in which folks who read the blog but rarely comment were invited to bust out of their shell a little bit, say hi, and tell us why they think the blog is so wonderful. (At Cosmic Variance, we're all about positive energy.) Now we are informed by Dr. Free-Ride that the second week in January has been declared De-Lurking Week. A whole week! Just to de-lurk. Seems a bit extravagant, but we must go along with what the blogosphere orders. So leave a comment, especially if you usually don't. This should fill some time while I am presently too busy to complete planned posts on gourmet chocolate, how to write a research paper, path-dependent utility, nationalism, understanding, moral humanism, and the beginning of the universe. There's some incentive for you. Note: Following Phil Plait's suggestion, we're experimenting with the wp-cache plugin. This speeds up performance by storing pages in a cache, rather than dynamically generating them each time they are accessed. The downside seems to be that comments don't show up as long as the pages are cached. So we've set them to be cached for about three minutes, after which your comments should appear. There's got to be a better way...
