If you have others, I'd love to know about them. You can log in with the guest account (edtechpost_guest, same password) or email them to me at edtechpost@gmail.com."

"Social bookmarking sites like Delicious are useful for collecting bookmarks, but they don't allow users to really draw connections and tell stories. That's where curation-focused services like Pearltrees and Trailmeme come in. Trailmeme, which we first looked at in December, was incubated at Xerox and launches at DEMO this week. It allows users to bookmark sites and then organize them in tidy diagrams, making it easy to highlight the relationship between different items and for readers to browse these links."

Twitter Set Theory & The Wisdom of the Group Wednesday, April 9, 2008 Several weeks ago I was introduced to an idea that I have found to be profound in its simplicity but complex in its implications. In an informal discussion about educational technology at EduBloggerCon West, Steve Hargadon described the kind of learning that is taking place in today's social networks. Interestingly enough, I caught the discussion via Ustream (and participated remotely within the Ustream chat), demonstrating yet another facet of this idea. I will paraphrase what Steve has come to call "the wisdom of the group": You don't need to have everybody in the room in order to have a good conversation. In other words, once you reach a certain number of people - local experts, if you will - you can have very rich dialog without requiring that all of the experts be present. Steve has found this to be true in many of the social networks that he frequents, and I have found it to be true in Twitter. In the days following our discussion, I have drawn up several diagrams that I think demonstrate additional dimensions to this concept (they also fit in nicely with this fine collection).
