I realize that while Twitter is a great place to listen and lurk, it may be an odd place to lengthen time, to stretch out a conversation of ideas. I wonder, for instance, which approach benefits students more – a real-time tweet session in which ideas, questions, and answers swirl in the air all at once in a dizzying yet stimulated hour, or a more leisurely session like the one I did with the students, in which ideas simmer over the course of a day, allowing them to stick and resonate?
