What do 'beta' and 'experimental' mean when they're making money just the same?
A typical release cycle for software development includes something called the beta-testing phase. The idea is to improve the product by enabling users, rather than developers or professional testers, to provide feedback.
The relationship between the software company and the beta testers is usually based on barter. No money is exchanged. The software company gets test services from the user, and the user gets familiarity with an upcoming product, familiarity that may provide some personal or professional benefit.
