Techmeme, the influential aggregator of technology news, has added another "human" element to its engine with Rich DeMuro, a veteran CNET editor who joined Techmeme earlier this year. Rich joins editor Megan McCarthy, the "first human editor" who started early last year. I caught up with Rich last Friday at the paidContent 2010 event in Manhattan. In this interview, he talks about the influence of Techmeme and provides insight on how stories surface on the site. Rich is based in Los Angeles. Andy Plesser, Executive Producer Less
