So I tried to look into the numbers. Their data collections is based on usage from "over 40,000 websites" and the actual methodology is hidden. I will make the assumption that most people who install and use Firefox and Chrome take additional steps to further secure the browser (noscript, Do Not Track Plus) Both which would prevent the data collection. Now, Linux users are generally either on the high end of computer experience and are much more likely to have additional security features or are non experienced users on systems set up by the high end users specifically to provide security.
So if you are seeing 1% market share for Linux. How many more computers go untracked?
IMO Mint or Lubuntu should be the default desktop on most of the home PCs out there. I have converted plenty of my non-technical friends and relatives to Lubuntu. The interface is similar to windows. Most of the configuration settings they use are GUI driven and easy to use. As far as the author saying Linux was more difficult, most of the issues he complains about are easily resolved through a Google search and honestly have much easier to understand solutions than Windows. Those who have a lower computing knowledge would be better server being on Linux because they will end up with more secure systems that will be less venerable to user error. Plus teaching someone "If it asks you for your password and you don't know exactly what its doing, don't type it in" is a lot easier then teaching safe computing on a windows machine.
