Who says you can’t take Twitter under water? My learning at this week’s 140 character conference (#140conf) says otherwise. When I found out that famed oceanographer Jacques Cousteau’s grandson, Fabien Cousteau, would be presenting a talk, I felt like a kid again — I used to beg my parents to stay up late to watch his TV specials. Fabien, who along with his father Jean-Michel Cousteau host the PBS show Ocean Adventures, discussed how the emergence of the real-time web and social media has effected how he interacts with his audience.
