After posting "NetApplications report on Firefox stats", I sent an email to many of the news sites responsible:
So, I have to ask, do you just reprint press releases?
A single (possibly self-serving) source, questionable methodology (only NetApplications customers were counted), and no margin of error mentioned for a change of 0.64% ?
What does WebSideStory say?
What does Google say?
What does TheCounter.com say? (Two point increase.)
What does *anyone else* say?
A few hours later, I received an email from Sharon Machlis, Online Managing Editor of ComputerWorld:
Thank you for taking the time to write in (even with a criticism). That article was first published by our sister company, the IDG News Service, and I forwarded your message both to the author of the article there, the editor in chief there, and the news editor here who selected the article for posting. I do think you raise some valid points, such as the importance of margin of error and the usefulness of better explaining the pool where those statistics come from (NetApplications customers tend to be small and mid-sized businesses).

And, just over twenty minutes later, from Juan Carlos Pérez:
Thanks for writing. You bring up some valid points in your letter/comment to Computerworld. I'll keep your observations in mind next time I write about browser market share.
thanks again,Juan Carlos Pérez
