Messaging: Mobile's Killer App | stratēchery by Ben Thompson:

Conversations are never ending, and friends come and go at a pace dictated not by physicality, but rather by attention.

Great line from Ben Thompson on the importance of instant messaging.

He's one of the few pundits that's good enough that when I find myself disagreeing with him, I stop and take the time to figure out how (most likely) 1.) I'm plain wrong or (occasionally, if I'm thoughtful enough) 2.) we're not really disagreeing, but taking different tacks at thinking the same thing.

But absolutely regardless of my petty self-interjection, that's a well-written line that deserves some credit.
