Facebook addicts will, of course, tell you that the social networking site is full of ways to stay connected. You can poke. You can chat. You can write on your friends' walls. You can play Scrabble.
More to the point, though, you also have a decent chance of finding that cute girl who sat next to you in the fifth grade -- the one you haven't seen in 15 years. That, at least, was the function that caught the imaginations of Danish brothers Christopher and David Mikkelsen. Years ago, the two realized that a social networking platform might be a great tool refugees could use to help them find their families. Now, just a few months after the launch of www.refunite.org, the site has made great strides toward becoming the go-to search engine for displaced people around the world.
