You know when you're staring at an old family photo and have no clue who's standing next to Uncle Dan? So do 16 million other users, who have registered for MyHeritage, which takes those long-lost relative stumpers by scanning photos with cool face-recognition software to build online family trees. Genealogy enthusiasts can use the Smart Matching technology to create their own family tree and link to related offshoots. Since the site launched last year, more than 100,000 networks -- with information on more than 150 million relatives -- have been formed to share family photos, events and news. Coming soon: a Look-Alike Meter, which will let users vote if Junior looks more like Mom or Dad.
