My Recent Searches gadget on the side bar was having a negative affect, I think. When perverts would do some sort of search that, due to my nature of using 'loaded terms', would land on a totally unrelated post, my system would link that post with those search terms.
The page would be crawled, and I think Google was starting to rank those results higher than necessary. It's like I was Google-bombing myself.
I noticed today that there were some pretty illegal searches going on for underage nookie pictures. That's not something I want associated with my site, so I've killed the gadget and the results page. I'm still collecting search statistics, I'm just not publishing them online any more to prevent any sort of confusion.
By the way, there's some weird people out there…
