A interesting bit of dialog with which I happen to agree:
What really got my attention was “the proportion of IE users here at ongoing recently crossed the 60% line, heading down”. Given the Tim Bray’s readers are largely early adopters of new technology, it is not much of a stretch to imagine that this represents the beginning of a tidal wave of change.
If you look closely at “Web Browsers Used to Access Google” in the Google Zeitgeist there looks like an interesting blip in the non-Microsoft browser numbers. Could this be the beginning of a larger change?
