Today, we're continuing with our series of wonderful interviews with women who have founded technology companies. We really love this interview series and are very excited about the person we're talking to today. With me is Larry Nelson from W3W3.com. Hi, Larry. Larry Nelson: & Hi. Boy, I'm really happy to be here. This is a wonderful series. It's extremely popular on our W3W3.com website. In fact, we archive all the interviews so you can go back and listen to them also. Lucy: & Also, listeners you can find this interview on the NCWIT website as well. Today, we're interviewing a very special person, Hilary Mason, who is the chief scientist at Bitly. We'll have to have Hilary explain it more precisely than I will, of course. But Bitly is primarily a URL shortening service, a bookmarking service. It really provides a fun and easy way to save and share and discover links from the web, by using links that they call bit marks. Reducing that URLs pretty important. Those things can get pretty beefy. You can't really share them very easily when you have only so many bytes that you can send along. This is pretty important to services like Twitter, for example, and others. Hilary's got a great job at Bitly. She's the chief scientist and her work crosses peer research, math and the development of product focused systems. Another thing we know about Hilary. She loves New York. Absolutely loves New York. Loves everything about New York, entrepreneurship, I'm sure she's going to tell us about that. She also gave one of my very favorite TED talks of all time, Replacing Yourself with a Very Small Shell Script, which I listened to several times. Hillary, welcome. Hilary Mason: & Thank you so much. Lucy: & Tell us a little bit about what's going on at Bitly. Hilary: & You gave a great overview of what Bitly is. But it's a fantastic example of something that is extremely simple that becomes quite interesting at a large scale. At Bitly, we see the links that people are sharing across all their different social networks. These are things like Twitter, Facebook, Tumblr, WordPress, Live Journal. Even strange places like YouTube or inside a virtual world like Habbo Hotel. Then we analyze the data in aggregate that comes from that social behavior. The kind of work that my team does is looking at human behavior through our social data. We work on things like building a search engine to try and find the most popular links about any topic you might be interested in. We also work on content recommendations. Some other really fun applications that are only possible because of the data set that comes from that very simple mechanism of shortening and sharing a link. Larry: & Wow. Lucy: & That's pretty interesting. All the social networking and sharing that's going on, we just redeveloped our website so we could more easily share our resources and also shorten our URLs. Very timely for us. Hilary, tell us a little bit about how you first got into technology and as you look out across the landscape today, which technologies do you find particularly interesting? Hilary: & The question about how I first got interested in technology was actually when I was a little girl. I was fascinated by computers. I taught myself to write code from reading the back of magazines when I was still in elementary school. I remember my first program. It was the Absolutely Wonderful 10 Print Hilary is Great 20 Go to 10 Run. [laughter] Hilary: & I thought it was amazing because it was an infinite loop and my teacher had no idea how to turn it off, who was even funnier. Lucy: & I know, infinite loops are pretty funny anyway. Larry: & Yes. [laughter] Hilary: & Yes, so I've always been f
