In reply to Troy Patterson.

Hi Troy, I am a primary teacher. I do use Twitter to post about what we do in class. I got on Twitter quite early because of the edtech community that was building there. I think, like many technologies used in Edu the adoption was not particularly thought out in advance but muddled through. It started as a place to have quick chats & post pointers to other content. It has become, for some, the main conduit to parents. I understand the affordances but worry about the cost.
