Earlier this week I was engaged in a spatially interesting exchange, in which I was discussing the contents of a blog post with Chris, next to whom I sit here at SHU. The post, authored by Naomi Barnes, had been brought to my attention in a tweet by Aaron, made accessible by the url he had included. Knowing Chris’ interests and current writing, I thought the post might interest him, so I mentioned it … old school … the spoken word. He asked if I would forward the details, which I did by sending an email which contained only the url. Having read the post, he then tweeted his interest and thanked both me and Naomi … which then set in train a flurry of replies, retweets and likes. And one hat-tip.
