What experience do you have with a "pay what you want" model (that is - when the user can choose how much to pay for your product) or revenue through "tipping services" like BuyMeACoffee? - What has your approach been? Is it more of a "maybe not worth charging for this, but making it open for donations anyway - because who knows!?" - or a deliberate strategy? - Was it completely voluntarily or did the user have to make a choice to e.g. access certain features or download something? - Any examples of when it did generate more revenue than expected? - Examples of when it completely failed? Would love to hear!
