Rachel at grasping for objectivity in my subjective life gives us a detailed list, with commentary, of the Google searches that led to her blog. Read and enjoy.
Probably the three most common searches that I get are "how to stop being Catholic," "savory sweet potato pie," and "bearing in mathematics."
The sad thing is that I could probably provide some kind of a useful answer for all three of these seekers. I might have to crack an old set of class notes about lubrication flow. But I wouldn't have to crack a cookbook or a volume of canon law.
