Some very smart thoughts on #newtwitter and decentralization by Alex Payne, who should know. I think it's a bit silly to refer to general micro-blogging as "lower case 't' tweeting", but I understand it and actually think it might be the most intuitive conceptualization for most people. That kind of thought is representative of Payne's smart take on "Twitter as a medium."
The anechoic chambers at Orfield Labs are the quietest place on Earth, at -9.4 dBs. (Yes, -dBs.) I highly recommend the experience of spending a few minutes in an anechoic chamber, if only for how bizarre it feels.
