I feel like my definition of MVP is different. When did MVP become "marketing landing page and mocks"? I'm not discounting the strategy. I think getting the idea in front of eyeballs to see if it is worthwhile is great. I'd even recommend it. I just don't think it is an MVP. You don't have a viable product yet if customers can't buy it. I'm just curious if this definition is common. My definition is: a product that has the minimum set of features implemented possible in order for people to be able to use it.
