Robin Good: Start this video clip at 1':42" (up to 3':30") and you can get a pretty good idea of what a content curator does and why what he does has so much to do with sense-making, making things understandable for others and ultimately extracting contextualized "meaning" from information "as is".
Must-see. Excellent. 9/10
P.S.: Thanks to Howard Rheingold for spotting this clip and sharing it.
