This is part one of a two-part interview with @Rabble (Evan Henshaw Plath) -- activist technologist, co-founder of Indymedia, and one of the originators of Twitter. We discuss the origins of Twitter in the protest organisation tool TxtMob; Evan's work developing Indymedia and the early days of tech's interaction with activism; how social media is continuing to mutate politics, for better and worse; how the sorting algorithms developed by Big Social are becoming indelibly embedded in our world -- and finally Evan introduces the subject of part two: Silicon Valley's hidden mission to restructure the world's institutions via software.
