All this surely contradicts my argument that Twitter, if not actually dead, is limping awkwardly towards an uncertain future in HE?
I can't help but contrast its extraordinary vibrancy in some spheres - think Trafigura or, closer to home, the success of Twitter enabled backchannels at conferences - with its relative flatness in HE for undergraduate teaching and learning.
Can technologies - and the extra they bring users in one sphere - transfer from one context to another? I used to think so but am now not so sure. Twitter is a great technology - my personal favourite - but it struggles against what I think is a technology cultures of undergraduates who see it as a broadcast tool to subscribe to celebrities.
