Submission + - Linux desktops, stand up and be counted! (dudalibre.com)
With this initiative, we intend to refute the statistics of certain press organizations that ensure [sic] that the use of GNU/Linux does not exceed 1% and has not advanced in recent years at the desktop. If you want to help us accomplish this goal, please participate in our statistics!
They're trying to do this by collecting ten million email addresses of desktop Linux users. If you're in that group, and you're ok with their privacy policy and want to be counted too, then why not sign up?
