What does this even mean? The "dumb algorithm" here will (a) take a user's query and (b) search that user's friends and public profiles for hits on that query. What's next: shouting about the robots taking over? Lamenting about how we're all losing our humanity and man weren't things better back in the old days?
I'm really disappointed this is the top comment on HN's top post. Users identified by Graph Search have public accounts and have willingly entered personal information into Facebook. We go thorough this song-and-dance every year: FB updates security policies, everyone is up in arms, then -- gasp! -- everyone updates their security settings. Facebook has a clear transaction with users: build a profile, get sold as eyeballs to advertisers. If you don't like it, then quit.
"With great power comes great responsibility," indeed. People have received numerous warnings about Facebook and privacy, and yet they've chosen to share personal information with everyone they know. At this point the user is responsible for choosing to participate or drop out. Meanwhile, every third HN post includes a commenter, wagging their finger, reminding us in a nasally, know-it-all voice that we're not the customer if we're not paying.
Is Graph Search really that shocking to you--to anyone on HN? Why the hell is anyone up in arms about this in 2013, given what we know about social networks?
