In the months before I made wiki, we had been having an argument. I think Kent Beck and I were on one side. People who had a lot of faith in the prevailing dogma of software engineering were on the other side. We said, "Collective code ownership is good." They said, "That's ridiculous. You'll never get responsibility. You'll never get quality if you don't have responsibility. And the only way you'll get responsibility is ownership. You have to pin the bugs back on somebody if you want them to ever rise above producing bugs." And I said, "Well that's wrong."

 
Ward Cunningham
 

There are no significant bugs in our released software that any significant number of users want fixed. … I'm saying we don't do a new version to fix bugs. We don't. Not enough people would buy it. You can take a hundred people using Microsoft Word. Call them up and say "Would you buy a new version because of bugs?" You won't get a single person to say they'd buy a new version because of bugs. We'd never be able to sell a release on that basis.

 
Bill Gates
 

I would like to go for a ride with you, have you take me to stand before a river in the dark where hundreds of lightning bugs blink this code in sequence: right here, nowhere else! Right now, never again!

 
Amy Hempel
 

A bug! A bug! Isn’t it just so satisfying to discover bugs in other people’s programs? Especially people from Microsoft. I don’t know why, it’s probably some kind of Freudian code-envy thing.

 
Paul DiLascia
 

Beloved, you that have faith in the fountain, frequent it. Beware of two errors which are very natural and very disastrous; beware of thinking any sin too great for it; beware of thinking any sin too small.
