Tie this to the trend of decreasing Internet Explorer usage noted late last week and the release of Firefox 3.5 RC1 and Safari 4.0 and Opera 10 in the last few weeks, and it appears that the balance of browser usage on the Internet is becoming more fluid.

Does this mean that standards will become more relevant? Can you truly count on limiting customers to one browser?

Will browser lock-in for certain applications continue to be considered acceptable?
