Last night, after the Canadian election party leaders’ debate, the analysis had a section where they graphed Twitter responses to various verbal sallies and bons mots. Innovative and useful I thought; admittedly a bit left-leaning, if only because smart well-connected young people tend to lean left. Then when I got to work this morning, someone sent me a pointer to Charles Arthur’s What effect will the financial crisis have on the tech sector? in The Guardian; it quotes my Twitter stream, twice. Once again, the spectrum of human communication shifts perceptibly.
