interesting. how would you make it better?

Clear APIs and better semantics. Another post points out how gross mistrust gets in the way but there are alao little mistrusts. For instance if there was an API to compare restaurant menus and order things through an agent that moves power up to the agent who can influence who gets the business.

That is, I'm not afraid of being branded subversive because I like to eat strange foreign foods, I'm afraid that I'm going to get the worst pizza in town instead of the best pizza in town because somebody paid off Apple or because Google or Facebook can put up a tollbooth in front of new entrants or that they might not be interested in working with or being fair with independent restaurants because private equity has bought most of them up.
