The importance of focusing on your audience's needs and providing context and relevance, not just aggregation, to really get value from content curation.
It's one of those issues that sounds straightforward until you're in the thick of it and the temptation is to add more, just because you can and it takes time to do it well.
Robin Good, an expert at content curation himself is quoted in the article:
"Are we creating and leveraging these tools to regurgitate and spit out more noise, or are we working to build tools and to help others understand the value of distilling and making sense of the information wave surrounding us?"
That seems as relevant a question for internal communications as it does for marketing.
