it seems to be really good with fictional characters from tv shows, but not so good with real people...
it got: sayid, hurley, richard alpert, & benjamin linus from lost, walter & astrid from fringe, betty & joan from mad men, nancy & celia from weeds, tara from true blood, christian from nip/tuck, olivia benson from law & order svu, & monk from monk...
and it got those with surprisingly little information...
