This is a short post, written by Sean Carton, (I'm posting his next article after this one) but he gets right to the point in this piece:
"Curation comes up when search stops working and when people realize that it isn't just about information seeking, it's also about synchronizing a community." Sean goes on to add that it's the "community" part that's at the heart of the whole curation movement
Just as a carefully-curated museum exhibit is sure to draw like-minded people together, carefully-curated content on the web has the potential to attract (and/or build) an online community of people who are into the same stuff."
Think about your niche and help the community make sense of its niche. Provide an ongoing resource (not just an event) and offer an attractive user experience.
