"How to quit XXX" can mean many things.

* Smoking: How to stop a nicotine additiction

* Alcohol: How to stop an alcohol additiction

* Vi: How to end the program once you have started it out of curiosity. (Hint: Kill process from another console and never look back)

* Facebook: How to find the hidden options to erase your account and data.
