Yesterday Google+ created shareable, public circles. And, as power user Robert Scoble suggested, engagement and usage has surged. In less than a day, I've had over 1,000 people follow me. That is entirely attributable to the new shared circles which are facilitating easier and more effective 'findability'. When people like Scoble curate lists for themselves - and then choose to share them publicly - they are clearly high quality.
