What I often hear and read is the phrase "Linux is not user friendly", or other phrases in which some lack of something is subject of complaint. Although I might have some understanding for these misgivings (dependant on the circumstances), it also seems to me that folks stating as such don't have a clue about what "Linux" actually is. It is not an Operating System (OS), nor a component of an OS that users directly interact with. So there is no need for Linux to be "user friendly", because it runs - as a manner of speaking - "under the bonnet" ("under the hood" for Americans). It is a system kernel, of which the name is in this case used as an umbrella name (to refer to the OS family or platform as a whole). This name is "GNU/Linux", sometimes simply "Linux".
