As a digital marketer who has shared responsibility for PR I find Twitter has helped bring some good PR contacts. I especially find the list feature of Twitter the most useful way to consume from the fire-hose ! I have multiple personal lists I maintain of influencers (journalists, execs, and developers) in the domain I track - SaaS, SaaS marketing, multiscreen video, and mobile marketing.
