Reading, writing, tweeting?

I just read on eSchoolNews a story about an elementary school in which the students are tweeting-- at the end of the day, along with their teachers they are publishing on social media.

Hmmmm... kind of changes the dynamics of "tell me what you did at school today..."

Am I alone in thinking that there are a large (and increasingly irrelevant) educators who would react to this with some discomfort? Contrary to the common perception, also, those who would react with discomfort are not necessarily the older teachers!
