Just an added thought... I am finding that curation using the comet method provides a really great intrinsic circular feedback system too because not only am I being more considered and thoughtful in my responses in the comments to others but I am at the same time examining my own comments and explaining / summarising back here in comet's world, the meaning in and behind my engagement. It provides an additional reality check for me and sometimes whilst updating the comet post, I find myself going back to my original comment to clarify or add something of more significance that my own self analysis has revealed is lacking. It really is insightful!
