We tell people we use Linux because it's secure or it's free or it's customizable or it has excellent community support.
But all of this is just marketing bullshit. We tell that to non Linux users because they wouldn't understand the real reason and when we say those false reasons enough we might even start to believe them ourselves.
But deep underneath , the real reason remain - We use Linux because it's fun! It's fun to tinker with your system. It's fun to change all the settings, break the system, then have to go back to recovery mode to fix it.It's fun to have a 100 distros to choose from.It's fun to use command line.
Let me say that again - it's fun to use command line.No wonder non Linux users won't understand.
The point with Linux fan is we use Linux for it's own sake.Sure, we like to get work done. Sure, we like to be secure from virus.Sure, we like to save money but these are only the side effects.What we really like is playing with the system, poking around and discovering fascinating facts about the software that lies underneath it.
