This occurs every now and then...legit comments without copious numbers of links get caught in the spam filter. Regular commenter Michelle has had her comments tagged as spam twice since she's changed her back-link URL to Scientific American. Today she tweeted me, and I noticed 4 other people who were also false-positived in the filter. To my knowledge these were all people whose comments I'd approved before. If your comment doesn't show up after 24 hours (or immediately if you are a regular who has been approved already), please feel free to ping me via twitter, facebook, or email me at contactgnxp -at- gmail -dot- com. I apologize in advance for the inconvenience. There's no way I can scan the spam manually, since there's always thousands of fake-comments about how awesome my blog is in passable English to wade through. So make sure to tell me what your handle is.
