"Curation" is the latest buzzword in educational technology (and many other industries), and I want to confess that I have struggled a bit with my understanding of it. When trying to explain it to a colleague, I actually said, "uh...like...the Big Dave burger at Wendy's is an example of curation..." I'm not sure my analogy was a winner. The cartoon which appeared in Dilbert (see below) soon thereafter hit home for me (and most likely my colleague.)
A great deal of my guidance in the curation movement has come from trainings from Indiana DOE rep and edtech demi-god @YancyUnger and his Getting the Horse to Drink blog. Yancy describes curation as moving our content out of a warehouse and into a museum. Many times as educators we try to share EVERYTHING about a topic, instead of picking out the major points and elevating them in a meaningful way. 
I am guilty of sending my teachers an email weighed down with websites with the heading "GREAT STUFF!"(warehouse) I can now see that this email was most likely met with a sneer, followed by the delete button. My teachers would be much more likely to give me some of their precious time if I send one website or resource with a brief explanation of how they might incorporate it into their curriculum (museum).Now that I have finished reading A Whole New Mind by Daniel Pink, I feel that my understanding of curation is finally complete. To summarize, the use of our left brains has led us to an age of prosperity and ease of information. Success today is less about memorizing (left brain) the content, and more about designing or curating the content (right brain.) This doesn't mean that we don't have to know what we're talking about. It means that in the 21st century we have to know our stuff, and be able to make it look pretty as well.
With this reasoning, it would be irresponsible as educators to take on a "content is king" attitude with our students. Yes, content is important, but remember that (with every kid carrying a computer in their pocket) facts are free. Content can be King as long as Curation is Queen in a marriage of equals.
Sort of makes you think twice about cutting those art teachers...
