Dave Winer – What will become of Twitter?:

"Twitter is a wonderful solution to many of the problems we had with RSS, most importantly, how to go from the impulse to subscribe to having actually subscribed. In Twitter it's one click. In RSS, it's an unpredictable number of complex clicks. That in a nutshell is why Twitter blossomed.

[…] It always takes longer than you think it should, but eventually the open formats and protocols replace the systems built on corporate training wheels."
