IBM has been over the news lately with news of how FireFox is being recommended internally, and 10% of its 300,000 employees are using it.
IBM is a computing company (mainly software and consulting). Natonal acceptance rates for Firefox are about 5%. So it actually is surprising how LOW the acceptance rate for Firefox is given the (hopefully) early technology adopting of a tech company.
I can virtually guarantee Google's Firefox usage rate was at least 25%+ last summer. Y'know, 12 months ago. We had issues in my group that some of the stuff rendered slightly wrong in IE and the developers didn't notice because we all used Firefox.
So let's start writing news articles like "Tech companies, which should have Internet Explorer strictly for testing how pages render (because they know better), still have more than 50% of their users using an old, buggy, spyware-prone application."
We're the people calling out for the average net user to stop using IE, yet the average user at our tech companies aren't adopting it.
