About a year ago, tech news aggregator Techmeme hired Megan McCarthy as its first dedicated human editor. Founder Gabe Rivera clearly liked the idea; he's now added three more. Rich DeMuro (formerly of CNET), Lidija David (formerly of ReadWriteWeb) and Mahendra Palsule (a former IT project manager) all join McCarthy to make up the editorial staff for Techmeme. Rivera notes that this team means they basically have human eyes watching for the best tech news 24 hours a day now. This allows Rivera and his fellow programmer, Omer Horvitz to keep the backend and the algorithm rolling.
