A reader noted that a comment he posted earlier in the day had not appeared. It turns out the Akismet spam filter used by this blog (and many others) is a little overzealous, and has categorized a number of legitimate comments as spam. My apologies. Until the filter problems can be corrected, I would request that if you post a comment that doesn’t appear, send me an email and I’ll look into it; if it’s caught by the spam filter it’s easy to rescue it. (One interim recommendation: very long posts appear more likely to be flagged as spam than shorter ones, so keep your comments to the point and instead package the long comments into essays to submit to The Space Review…)
