What do you care about? I use Twitter to learn about, and share what people are doing to make the world a better place. I'm interested in everything related to space, but also scuba diving, piloting aircrafts, anything electronics and photography. We're interested in music, (beatboxing) news and funny people. [inaudible] Who do you follow? The best way of finding out what my guests are up to before they come on my show, is to follow them on Twitter. This is exactly what I do. I follow Green Day on Twitter because I always like to keep up with what they're doing. They're my favorite band. I wanna stay up-to-date on fashion news, so I follow @styledotcom and @womensweardaily. I like to follow Martha Stewart because she keeps it scutted and butted, baked and flaked, and she loves to wake and bake with the big Snoop Dogg. Ya feel me? What do you want to know? It's always good for us to know what people want, and I use Twitter as that, as a way of learning what I should do, what fans want, because they're the best critics. I can talk to the fans, they can talk back to me. Fights they wanna see, things I'm doing wrong, how stupid I am. Whatever the deal might be, I can communicate directly with our fans through Twitter. We really like to keep tabs with our other partners in conservation the other zoos and aquariums here in North America. How do you explore what's out there? I'm using Twitter to send pictures and thoughts from space and everyday I really enjoy reading your Tweets. Ciao to all of you on the beautiful planet Earth. People can exchange ideas and information instantaneously. Countries and cultures are brought together like never before. What's cool about Twitter is that you can get a lot of different information in real time. I love using Twitter because I can connect with all fans, all around the world. I wanna listen to the American people, so I follow thousands. I use Twitter to keep in touch. Really, I use Twitter to listen. Follow your interests. Discover your world.
