The central point is that "viable" doesn't really apply to a huge class of products and things. There are times when a user wants a problem solved, but in other instances they are looking to add a little something inessential but pleasant/fun/nice/funny/beautiful/lovely to their life, even just a moment to connect thoughts or with other people, not because of a job offer or order pizza, but to add variety to life. In the morning do you just cover up, dress appropriately or love fashion? There are businesses placed at many points in Maslow's hierarchy. Software is going to be completely omnipresent and there will be fewer exciting startups tackling problems at the bottom of the pyramid. Look at the facebook valuation. For that business, they will have needed an MDP. Talking about minimum viability of social networking software is a muddled discussion. That is why I like the idea of MDP. Nice observation.
