Re: What do you use Ubuntu for?
To answer this question, I have to ask you a question that's nearly the opposite of what you asked me:
What do you use Windows for?
I use Linux for whatever you use Windows for.
A much quicker question to ask me is "What do you use Windows for", to which I would reply "The only thing I can't use Linux for: Filing my Australian tax return electronically. And even then, Windows is only inside a virtual machine."
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
