It's important to note that no one can 'stalk' you using this feature if they aren't your friend - you can't search by name, only content. Unless there is personally identifiable information about the person in the post itself (e.g. "I'm John Doe and I hate my boss Bob Smith") the odds are you'll never be able to find information about the person you are looking for. If you search for "rectal exam" (http://willmoffat.github.com/FacebookSearch/?q=rectal%20exam) and you happen to know Groten Nils, well, that's pretty embarrassing.
