Anyways... Made me wonder who he was and that, and in perusing his blog came across this article about life and the meaning of twitter.
Pretty good. Presents some ideas about limitations to the value of nearer-instantaneous communications (and interaction v broadcast) other than the usual 'verbal diarrhoea' argument.
It does have a bit of unnecessary wrap-up at the end, but it would still be a great article if broke off on the paragraph ending,
"We could spend our whole lives texting but there will always be part of us that is infinitely remote."
