Eric Raymond
“Given a large enough beta-tester and co-developer base, almost every problem will be characterized quickly and the fix obvious to someone.” (Raymond, “The Cathedral and the Bazaar,” 2000)
“Release early. Release often. And listen to your customers.” (Raymond, “The Cathedral and the Bazaar,” 2000)
“Treating your users as co-developers is your least-hassle route to rapid code improvement and effective debugging.” (Raymond, “The Cathedral and the Bazaar,” 2000)
“Every good work of software starts by scratching a developer’s personal itch.” (Raymond, “The Cathedral and the Bazaar,” 2000)
“The next best thing to having good ideas is recognizing good ideas from your users. Sometimes the latter is better.” (Raymond, “The Cathedral and the Bazaar,” 2000)
James Surowiecki
“In the absence of hard evidence to the contrary, it’s easier for individuals to create explanations to justify the way things are than to imagine how they might be different.” (Surowiecki, “The Wisdom of Crowds,” 2005)
