The page you came from is a weblog: a collection of random items about things I've found while wandering around the Internet. As I add new things at the top of the page, the older ones get pushed off the bottom. It's entirely possible that what you were looking for isn't on the front page of the weblog any more, but of course there's no way to tell the search engines that.
You might like to try repeating your search on this page, which searches through past weblog entries.
