Hilarious--there was a fellow co-op student I hadn't heard from in 6 years, and I couldn't find his contact info, so I decided to spring a "googletrap" for him. That is, I posted a blog entry for him to find when he searched for his name.
And 18 months later, he happily did, and got in touch with me.
There must be an existing term for this sort of "googletrapping" or "futuresearching"--basically, having found no search results to one's satisfaction, creating a blog entry for future searchers to find and contact you about with the desired information. Works great for error messages that turn up no search results--you post the error message in a blog entry and some months later get an email from someone who "was getting the same error message and here's what I did", or at least was getting the same error message, like you has no idea how to solve it, but offers sympathy and condolences.
