A great introduction to what digital curation is all about, with some specific hints and tips on using Scoop-it, one of the leading digital curation tools. For those who are still confused about the difference between "aggregation" and "curation", this quote from the article neatly sums it up:
"Scoop.it is not just another place to drop your RSS feed. It could be, but then it’s just another content aggregator. Content curation, on the other hand, is much like museum curation. The objects in a museum have value, for whatever reason – historical and artistic beauty are just two I can think of off the top of my head. These objects are carefully displayed, carefully picked over – less than half of what comes in to museums actually gets shown for public consumption."
This is a recommended read if you're new to digital curation, or want a few easy to follow tips for using Scoop.it.
