If you’re on a beat, you want to be THE source for news on it. Generally, that means you’ll get beaten on being first to a story. No worries: RT them, then blog it, and link in articles. Over time, people (and algorithms) will value you for that work.
Any entity that distributes content online — whether they’re in the media, government, academia, nonprofit or other organizations, needs to be thinking about search engine optimization (SEO) and social media optimization (SMO) in 2012. Any policies that force journalists into internal silos will eviscerate that capability.
A RT is social media currency. Instructing journalists not to give them out where deserved is like sending them into a conflict or disaster zone with no funds for a fixer, fuel or food. It’s not just bad form. It’s bad business.
