You're fast on your reply and tweet! I think that even if a Scoop.it user starts as a "collector," we've built the product to help the him become better at curation -- and perhaps turn him into a "(Robin) good curator."

We also give points to our users to incentivize them to do better curation. These points are measured not by the amount of posts on their topics but by the insight they've added to each piece of content and the quality of engagement they've received from each piece they've curated. Here are the curators with the top points on Scoop.it -- http://www.scoop.it/search#topQualitySectionSelected. Our data shows that as the user becomes a better curator, they become more likely to add and share their own insight, which I think is part of "sense-making."
