On this week's Bytemarks Cafe, the weekly science and technology radio show I co-host with Burt Lum on Hawaii Public Radio, we had the honor of interviewing George Takei. He's best known for his role as Sulu on Star Trek, but he's also been a long-time, prominent, and outspoken advocate of the Asian American community as well as for the Gay, Lesbian, Bisexual and Transgendered (GLBT) community.
