A slide show following the social networking phenomenon ends up concluding that the networking tools available today are helping people get together. From my own use of the social media tools, I have learned enough about someone so that when I do meet them in person, the conversation doesn't have that expectant pause. After we have greeted each other, the question "where do we go from here?" doesn't come up. We are already deep into a conversation.
Thanks for the link to Education Innovation and in particular to Angela Maiers for the tweet tip.
