An idea for an interactive recipe hosting service.

There is a certain number of services for placing aphorisms on them, catch phrases, etc. from any literary works. Examples are “Textik”, “Great Words”.
By their principle, you can create a service for placing recipes and their collections. These can be recipes from books on psychology, economics, etc. For example, I was engaged in writing out those in notebooks after reading a book. For “Economics without secrets”, I. V. Lipsits - this was a list of recipes for economic prosperity, and for “Six ways to win over people” by D. Carnegie — it was a list of the methods themselves.
What is it for? First, it can be useful to those who read the book and occasionally wants to use the main thoughts from it in a brief presentation. Secondly, it can be useful for those who have found for themselves some kind of book on topics of interest to him, but from the desire to save time, it will be enough of her abstract study. Thirdly, it will be a godsend for those who are just used to using formulated ideas, without going into their essence and relying on their intuition.
What do you think about this idea and does anyone have an opportunity to implement it (I don’t have one yet)?
