Hello Harold,

Great article. I have been asking myself this question since a friend wrote me saying that a very sensitive issue he had shared was tagged as Entertainment by the robot of Paper.li

I've just helped to put together a new structure to share articles and news I and other colleagues read. I feel there is a higher potential of value creation because many people can be curators together, sharing a collective, in our case, Tuesday's Finds. It is at http://news.hostinglearning.com

Your article made me realise that there's more to be done in terms of annotation rather than clipping - so I'll spread the word and improve what's there. Thanks!
