After another M$ win failure more and more users are going to choose linux. But for a new user the ideology "We are the best and we don't care whether you like us or not." is hard to adopt. I mean there are lots of people who for some reason don't like windows or mac. If there is a easy documentation that teaches them on linux basics - for example - how to install drivers, how to install skype, how to search for programs, helpful links, which are the alternatives on the windows programs they use daily and so on. Then the user will see that linux is not so hard or different from win or mac and linux people will multiply. This documentation/user guide/linux mint cookbook/definitive guide can be translated to other languages by volunteers.
Some people think that it doesn't matter if linux has 1 or 10% market share but they are wrong because if linux had for example 20% market share commercial programs and games should be written for linux too, drivers for devices etc.
