"100% Rails all the way, baby!"
I had been planning on using Java, JSPs, struts 2, and Hibernate Search - but decided to go with Ruby on Rails. I made this decision partly because I have been doing a lot more Ruby work than Java work in the last 18 months, and partly because I have learned some new Rails architecture tricks, and wanted to use them.
In any case, Carol and I want to create a healthy cooking web portal that will make a real positive difference in people's health and in their enjoyment of cooking and eating. I believe that the concept of seeing nutritional ingredients for recipes coupled with the ability to change ingredients on the fly and see changes in fats, sodium, vitamins, etc. will help people who either have dietary problems or simply want to eat healthier. If we end up making some money on CookingSpace that would be nice also :-)
