So... it's either algorithmic stalking or it's nothing that new, right? I'm going for algorithmic stalking. Now, to really be effective, I guess they're going to have to add "graph alerts" so one can get notified when (totally hypothetically), any friend of a friend living in the same city with more than n friends (to screen out the losers; replace n with your own threshold) changes her relationship status to "single". Or I guess one can just keep a saved search/smart folder of "prospects" (stalkees?) that can be "checked in" on from time to time; maybe set up a mobile alert that pings you whenever one of them is in/near your neighborhood. So, I can see why advertisers or businesses might like this, and I can see why grudge-holding exes might like this, but I can't really see why I would want to be stalked. Thank god Facebook has such transparent and persistent privacy settings, or I'd really worry! (yes, this is over the top)
