There are quite a few psychological techniques that can be used to influence others. There are however two problems:
1. There are many such techniques.
2. Sometimes it’s hard to imagine their application to your particular situation, especially when combining more than one such technique.
A book, where each chapter focuses on one technique, explains it, and then shows many specific applications in many fields, either by itself or combined with one or more of the other techniques. On online community could also be created for further discussions.
Most cooking websites and apps center around the recipes. This one is different.
Have a cooking community website that is organized around the user and not a particular recipe. When you look up a recipe, first you check the recipe publisher’s member profiles, and then their recipes. You can follow them to get updates, communicate with them, rate them and their recipes, etc. As a user, you can also publish your original recipes or your version of any recipe you think is THE recipe for that dish.
