The InformationWeek article that picked up the Radicati "report"...
... is no longer out there. You click on the story and you get the equivalent of a 404 error.
Now, today I did fill out their "letter to the editor" form and strongly suggested they check out Chris Byrne's article for an alternative view of the validity of the numbers and whether they could accurately draw conclusions from them. I'd really like to think that they did just that, realized that there were some serious issues, and removed the article. The proof will be to see if they do the follow-up report that was promised in the original article. If they don't write that piece and that's the last we hear of the white paper, then my faith in technology journalism will be somewhat restored.
With the exception of Forbes, that is... :-)
