Is John Edwards (or a staff droid) really using Twitter?
Ross Masyfield, who thinks about this stuff in a much more organized way than I do, says Twitter is tipping the tuna which is his code for a network good tipping into importance (but something less than hitting the bigtime).
Myself, I don't think twitter would improve my life. The last thing I need is more distractions and interruptions.
But it's an interesting phenomenon. “Only connect” morphed into “always connect”.
