However, jones sometimes seems to latch on to small pieces of information to prove his much larger, more sinister theories. For example, while were here, he says this about an article he found on cnn. Com. And they recommend having a onechild policy. Reporter and i looked up the article, and i have it. I can pull it up for you. Its actually a fluffy feature piece interviewing a woman who wrote a semijokey book about having environmentally friendly sex, in which she talks about doing dating and it slipped in there. It says we might want a onechild policy. Reporter yeah, but it was a sarcastic aside. See, its all sarcastic.

Tum tum tum tum tums today all eyes were on facebook as the social network finally unveiled the new project that, until today, had been shrouded in mystery. No, its not the phone so many have speculated about, but a new social search tool that threatens to invade the turf of google, linkedin and yelp. Facebook thinks it could change the way their billion users interact online, and abcs david wright brings us this exclusive behindthescenes look. Reporter today at facebook headquarters, founder Mark Zuckerberg launched a new era for the social networking site. One of the older traditions that we have at facebook. Reporter by holding up a gong. This little ritual happens only at big product launches of facebook, marking the moment the new product goes online. Facebooks tantalizingly vague announcement just come and see what were building. People guess Search Engine. Guessed facebook gifts. Guessed a facebook phone. Reporter led to a frenzy of speculation about what it might be. Maybe a standalone ipad app. Reporter not quite. Facebook gave nightline exclusive access to what theyve really been building, a rare behindthescenes look at a product that could change peoples daily habits online. Graph search, a powerful tool with an uninspiring name, a Search Engine like no other. So this is just some really neat stuff. This is one of the coolest things that i think that weve done in a while. Reporter until now, facebook has been sort of a hightech scrapbook people constantly update and share with their friends. But its really a giant data base, a billion people voluntarily sharing their likes and dislikes, voluntarily sharing 240 billion photos, voluntarily forging a trillion connections between all those items. Until now, you could browse only one page at a time. Now the whole data base is searchable, along with all those connections. Is this facebook trying to get into the Google Business . A little bit. Reporter if you think of google as the yellow pages, the encyclopedia and the almanac all rolled into one, basic answers to basic questions, facebooks new search tool is something far more personal. Here you get biased results. People are used to doing searches on the web, say, for a plumber. But youre not used to saying show me all the plumbers that my friends like. Thats almost like a holy grail, in some cases, for anybody whos ever tried to find somebody that they trust and they really want recommendations from other people that they know, because oftentimes you cant really tap into all your friends that way. Reporter depending on your friends and interests, some of your search results will be different from mine. What makes this different from a traditional web search is that the results are personalized to you based on you and your friends. So if i type tv shows my friends like, the results that come up for me are world news, nightline, good morning america. Go figure. Thankfully, the new tool isnt limited to just your friends. You actually search all of the data publicly shared on facebook. Lets say i want to check out if there are any italian restaurants in los angeles. Reporter project manager kate oneill showed us how you can filter the search further by cuisine, by location, even by your friends recommendations. That los angeles restaurant that residents have visited, that my friends have visited, and here we have one restaurant that i may want to check out. Reporter i can say firsthand thats a great spot. Thats great to hear. Reporter the pockets are endless and sometimes amusing. While they were dog fooding the tool, thats using it only amongst facebook employees, someone thought to plug in music liked by people who like mitt romney. Top result, johnny cash. I can change mitt romney to barack obama. Reporter top results there, michael jackson. Are you hoping someday this will replace google or not . Thats not i dont think thats the way we think about it. The way we thought about it is theres all this stuff that you shared about yourself, that you shared about your friends, that you shared about the world around you and were trying to unlock the value of that. And to make it all searchable. Reporter now you can collect together all your favorite photos of friends and family. Or ask it to show you all the photos of those people from long ago. Content personalized just to you. For now, the tool is limited just to four basic categories. People, photos, places, and interests. You cant search for things, for example, like posts, events. Those things are not currently included in this early version of graph search. Reporter will they be someday . Yes, they will be someday. If i, for example, met someone at a party, didnt catch their last name, but we talked a long time and i got a bunch of information in the course of the conversation, i could actually do a search like this. So people named russ who live in San Francisco and are friends with tom. And here, im getting back this person that i talked to, russ, hes a designer, we met at a party. Reporter did you really . Sparks flew . No, not like that. But russ is actually married. Reporter well, you get the idea. Facebook has digitized people and digitized our connections, not just with each other, but also with people, places and things. And now this is a glimmer to what you can do with that. New ways to waste time at home and at the office. You can say that, although interestingly you can also say that people have been wasting time on facebook before and this actually might make them more productive in some ways. Reporter quicker to find out. Exactly. Reporter facebook has been careful to reassure people the new tool respects all the Privacy Restrictions people put on their data. The engineers say thats one thing that made this project a challenge. Most of them, about 50 in all, have been locked in this room for a month. Reporter how many of you have slept here at least one night while this thing has been in progress . And how many of you have partners at home that are ready to kill you right now . Today the lockdown officially ended, the celebrations began. By the time they all get home, their friends and family, among the first to get this new toy, may be spending even more time on facebook. Im david wright for nightline. Well, as of tonight, graph search is already available to a limited number of facebook users and will gradually be extended to everybody. Just ahead, doing hard time with needles and yarn . The unlikely success of knitting behind bars. It doesnt matter which of our great states folks visit. Mississippi, alabama, louisiana or florida, theyre gonna love it. Shaul, your alabama hospitality is incredible. Thanks, karen. Love your mississippi outdoors. I vote for your florida beaches, dawn. Bill, this louisiana seafood is delicious. Were having such a great year on the gulf, weve decided to put aside our rivalry. Now is the perfect time to visit anyone of our states. The beaches and waters couldnt be more beautiful. Take a boat ride, go fishing or just lay in the sun. Weve got coastline to explore and wildlife to photograph. And theres world class dining with our world famous seafood. So for a great vacation this year, come to the gulf. Its all fabulous but i give florida the edge. Right after mississippi. You mean alabama. Say louisiana or theres no dessert. This invitation is brought to you by bp and all of us who call the gulf home. Is the same frequent heartburn treatment as prilosec otc. Now with a fancy coating that gives you a burst of wildberry flavor. Now why make a flavored heartburn pill . Because this is america. And we dont just make things you want, we make things you didnt even know you wanted. Like a spoon fork. Spray cheese. And jeans made out of sweatpants. So grab yourself some new prilosec otc wildberry. [ male announcer ] one pill each morning. 24 hours. Zero heartburn. Satisfaction guaranteed or your money back. [ male announcer ] this is karen and jeremiah. They dont know it yet, but theyre gonna fall in love, get married, have a couple of kids, [ children laughing ] move to the country, and live a long, happy life together where they almost never fight about money. [ dog barks ] because right after they get married, theyll find some retirement people who are paid on salary, not commission. Theyll get straightforward guidance and be able to focus on other things, like each other, which isnt rocket science. Its just common sense. From td ameritrade. Well, what do you think about hardened criminals serving time behind bars, you probably dont think about knitting. But in one prison in maryland, two retirees are turning dozens of convicts into converts with the help of yarn, needles and the zen of the stitch. Reporter barbed wire fences, watchmen towers and a group of men with convictions. Hardened criminals. This is no whitecollar country club. Im arrested for armed kidnapping. Attempted murder. Reporter but listen a little closer. I love knitting. Reporter and you realize theres more here than meets the eye. Im knitting a small hat for a kid. Reporter that softer side appears every thursday around dusk. With two unusual visitors to the prerelease unit in jessup, maryland. Meet lynn and sheila. You wanted to give knitting needles to hardened criminals. Is that a good idea . For a man to have picked up needles to walk through that door, to say come on, let me teach you thousahow to knit, to respond to knitting, theyve shown themselves as open people. Reporter would male inmates have interest in a hobby traditionally for women . Wrap it around. Reporter lynn and sheila still remember the department of corrections initial response. They dont want to knit. What makes you think men want to knit . I said they want to knit. They just dont know they want to knit. You like it, right . Reporter nearly three years later, the ladies have taught more than 100 prisoners to knit while dozens remain on a waiting list. Some of the inmates have even skipped dinner to make class. I feel calm. It gives you a peace of mind. It definitely do that. Give you a peace of mind. Takes you away from present. Reporter something to focus on. Pretty much. Reporter Nellie Proctor compares it to hanging out in the starbucks. This is like starbucks, without the coffee. Reporter just chilling . Just chilling. Enjoying the day. Gets you away from the penitentiary lifestyle. Reporter there will be people that will see this story and might feel like you should do hard time, and going to a knitting class might not sort of fit their idea of what serving a jail sentence should be. What would you say to them . Im doing something constructive. I could be doing a lot worse. To be honest with you. I could be running amuck, being a pain in the behind. I come in here to relax. They should try it and theyll understand. Reporter lynn and sheila give all the men a fiveminute knitting lesson she swears she can teach anyone. I had one of the guys put me through the paces. Wrap it around. You have to say it. Everything they knit goes to charitable causes, like these hats for students at troubled inner city schools. You know, we did a lot of wrong in society, so i guess this is a way of giving back. Reporter do you think youll continue knitting when you get out . Probably, in the house when im bored, i might do about 30 stitches. Reporter lynn and sheila say theyve seen their students change for the better. These guys are getting out. They can
