The screencast is a little lengthy at 20+ minutes (think of it as a “libraryside” chat), but I share some of the challenges of curating and sharing content to spaces for curation and reflection in one’s personal learning environment (PLE), including Scoop.it, Posterous, and Tumblr.  In this video, I also offer some constructive suggestions to database vendors for improving the “sharing” features of their resources to be more user-friendly.
